Most API methods are supported over the Websocket, HTTP, and MQTT
(if configured) transports. File Transfer and /access requests are only
available over HTTP. The Websocket is required to receive server generated
events such as gcode responses. For information on how to set up the
Websocket, please see the Appendix at the end of this document.
HTTP API Overview
Moonraker's HTTP API could best be described as "RESTish". Attempts are made to conform to REST standards, however the dynamic nature of Moonraker's API registration along with the desire to keep consistency between multiple API protocols results in an HTTP API that does not completely adhere to the standard.
Moonraker is capable of parsing request arguments from the both the body
(either JSON or form-data depending on the Content-Type header) and from
the query string. All arguments are grouped together in one data structure,
with body arguments taking precedence over query arguments. Thus
if the same argument is supplied both in the body and in the
query string the body argument would be used. It is left up to the client
developer to decide exactly how they want to provide arguments, however
future API documentation will make recommendations. As of March 1st 2021
this document exclusively illustrates arguments via the query string.
All successful HTTP requests will return a json encoded object in the form of:
{result: <response data>}
Response data is generally an object itself, however for some requests this may simply be an "ok" string.
Should a request result in an error, a standard error code along with an error specific message is returned.
Query string type hints
By default all arguments passed via the query string are represented as strings. Most endpoint handlers know the data type for each of their arguments, thus they can perform conversion from a string type if necessary. However some endpoints accept arguments of a "generic" type, thus the client is responsible for specifying the type if "string" is not desirable. This is not a problem for websocket requests as the JSON parser can extract the appropriate type. HTTP requests must provide "type hints" in these scenarios. Moonraker supplies support for the following query string type hints:
- int
- bool
- float
- json
The
jsontype hint can be specified to pass an array or an object via the query string. Remember to percent encode the json string so that the query string is correctly parsed.
Type hints may be specified by post-fixing them to a key, with a ":"
separating the key and the hint. For example, lets assume that we
have a request that takes seconds (integer) and enabled (boolean)
arguments. The query string with type hints might look like:
?seconds:int=120&enabled:bool=true
A query string that takes a value argument with which we want to
pass an object, {foo: 21.5, bar: "hello"} might look like:
?value:json=%7B%22foo%22%3A21.5%2C%22bar%22%3A%22hello%22%7D
As you can see, a percent encoded json string is not human readable, thus using this functionality should be seen as a "last resort." If at all possible clients should attempt to put these arguments in the body of a request.
JSON-RPC API Overview
The Websocket and MQTT transports use the JSON-RPC 2.0
protocol. The Websocket transmits objects in a text frame, whereas MQTT
transmits them in the payload of a topic. When MQTT is configured Moonraker
subscribes to an api request topic. After an api request is processed Moonraker
publishes the return value to a response topic. By default these topics are
{instance_name}/moonraker/api/request and
{instance_name}/moonraker/api/response. The {instance_name} should be a
unique identifier for each instance of Moonraker and defaults to the machine's
host name.
An encoded request should look something like:
{
"jsonrpc": "2.0",
"method": "API method",
"params": {"arg_one": 1, "arg_two": true},
"id": 354
}
The params field may be left out if the API request takes no arguments.
The id should be a unique value that has no chance of colliding
with other JSON-RPC requests. The method is the API method, as defined
for each API in this document.
!!! tip
MQTT requests may provide an optional mqtt_timestamp keyword
argument in the params field of the JSON-RPC request. To avoid
potential collisions from time drift it is recommended to specify
the timestamp in microseconds since the Unix Epoch. If provided
Moonraker will use the timestamp to discard duplicate requests.
It is recommended to either provide a timestamp or publish API
requests at a QoS level of 0 or 2.
A successful request will return a response like the following:
{
"jsonrpc": "2.0",
"result": {"res_data": "success"},
"id": 354
}
The result will generally contain an object, but as with the HTTP API in some
cases it may simply return a string. The id field will return an id that
matches the one provided by the request.
Requests that result in an error will receive a properly formatted JSON-RPC response:
{
"jsonrpc": "2.0",
"error": {"code": 36000, "message": "Error Message"},
"id": 354
}
Some errors may not return a request ID, such as an improperly formatted request.
The moontest repo includes a basic test interface with example usage for most of the requests below. It also includes a basic JSON-RPC implementation that uses promises to return responses and errors (see json-rpc.js).
Websocket Connections
Primary websocket
The primary websocket supports Moonraker's JSON-RPC API. Most applications that desire a websocket connection will make use of the primary websocket.
The primary websocket is available at:
ws://host_or_ip:port/websocket`
The primary websocket will remain connected until the application disconnects or Moonraker is shutdown.
Bridge websocket
The "bridge" websocket provides a near direct passthrough to Klipper's API Server. Klipper uses its own RPC protocol, which is effectively a simplified version of the JSON-RPC specification. Developers should refer to Klipper's API documentation for details on the protocol and available APIs.
!!! Note
The bridge websocket is described as "near direct passthrough" because
Moonraker handles the ETX (0x03) terminator internally. Applications
can expect to receive complete JSON encoded messages in a text frame
without the ETX terminator. Likewise applications should send JSON encoded
messages without the ETX terminator. Messages may be sent using either
text frames or binary frames.
The bridge websocket provides access to diagnostic APIs that are not generally
suitable for Moonraker's primary connection. These requests stream a
substantial amount of data; bridge connections allow Moonraker to avoid
decoding and re-encoding this data, reducing CPU load on the host. The "dump"
requests, such as motion_report/dump_stepper and adxl345/dump_adxl345, are
examples of APIs that should make use of the bridge websocket.
The bridge websocket is available at:
ws://host_or_ip:port/klippysocket
The availability of bridge connections depends on Klippy's availablility. If Klippy is not running or its API server is not enabled then a bridge websocket connection cannot be established. Established bridge connections will close when Klippy is shutdown or restarted. Such connections will also be closed if Moonraker is restarted or shutdown.
!!! Note If JWT or API Key authentication is required the application must use a oneshot token when connecting to a bridge socket. Since Moonraker does not decode bridge requests it is not possible to authenticate post connection.
Unix Socket Connection
All JSON-RPC APIs available over the websocket are also made available over a
Unix Domain Socket. Moonraker creates the socket file at
<datapath>/comms/moonraker.sock (ie: ~/printer_data/comms/moonraker.sock).
The Unix Socket does not use the websocket transport protocol, instead
it expects UTF-8 encoded JSON-RPC strings. Each JSON-RPC request must be
terminated with an ETX character (0x03).
The Unix Socket is desirable for front ends and extensions running on the local machine as authentication is not necessary. There should be a small performance improvement due to the simplified transport protocol, however the impact of this is likely negligible.
The moontest repo contains a
python script
to test comms over the unix socket.
Jinja2 Template API Calls
Some template options in Moonraker's configuration, such as those in the
button component, may call Moonraker APIs through
the call_method(method_name, kwargs) context function. The call_method
function takes the API's JSON-RPC method name as its first parameter, followed
by a set of keyword arguments as per the method's requirements.
# moonraker.conf
# Query Printer Objects example
[button check_status]
pin: gpio26
on_press:
{% set query_objs = {"toolhead": ["position"], "print_stats": None} %}
# JSON-RPC method is "printer.objects.query", which takes a single "objects"
# argument
{% set status = call_method("printer.objects.query", objects=query_objs) %}
# do something with the value returned from the object query, perhaps
# send a websocket notification or publish a mqtt topic
# Publish button event to MQTT Topic
[button check_status]
pin: gpio26
on_release:
# JSON-RPC method is "server.mqtt.publish"
{% do call_method("server.mqtt.publish",
topic="moonraker/mybutton",
payload="Button Released") %}
Server Administration
Query Server Info
HTTP request:
GET /server/info
JSON-RPC request:

}
!!! warning
This object also includes plugins and failed_plugins fields that
are now deprecated. They duplicate the information in
components and failed_components, and will be removed in the future.
Note that klippy_state will match the state value received from
/printer/info. The klippy_connected item tracks the state of the
unix domain socket connect to Klippy. The components key will return a list
of enabled components. This can be used by clients to check if an optional
component is available. Optional components that do not load correctly will
not prevent the server from starting, thus any components that failed to load
will be reported in the failed_components field.
The websocket_count field reports the total number of connected websockets.

Subscribe to printer object status
HTTP request:
POST /printer/objects/subscribe?connection_id=123456789&gcode_move&extruder`
!!! note
The HTTP API requires that a connection_id is passed via the query
string or as part of the form. This should be the
ID reported from a currently connected websocket. A
request that includes only the connection_id argument will cancel the
subscription on the specified websocket.
This request is not available over MQTT as it can not be set per client.
Instead MQTT can publish printer status by setting the `status_objects`
option in the `[mqtt]` section.
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "printer.objects.subscribe",
"params": {
"objects": {
"gcode_move": null,
"toolhead": ["position", "status"]
}
},
"id": 5434
}
!!! note
If objects is set to an empty object then the subscription will
be cancelled.
Returns:
Status data for objects in the request, with the format matching that of
the /printer/objects/query:
{
"eventtime": 578243.57824499,
"status": {
"gcode_move": {
"absolute_coordinates": true,

GCode APIs
Run a gcode:
HTTP request:
POST /printer/gcode/script?script=G28
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "printer.gcode.script",
"params": {
"script": "G28"
},
"id": 7466}
!!! warning
When M112(emergency stop) is requested via this endpoint it will not
immediately stop the printer. M112 will be placed on the gcode queue and
executed after all previous gcodes are complete. If a client detects
M112 via user input (such as a console) it should request the
/printer/emergency_stop endpoint to immediately halt the printer. This
may be done in addition to sending the M112 gcode if desired.
Returns:
ok when the gcode has completed execution.
Get GCode Help
HTTP request:
GET /printer/gcode/help
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "printer.gcode.help",
"id": 4645
}
Returns:
An object where they keys are gcode handlers and values are the associated help strings. Note that help strings are not available for default gcode handlers such as G1, G28, etc, nor are they available for extended handlers that failed to register a description in Klippy.

"cpu2": 1.02,
"cpu3": 1
},
"system_uptime": 2876970.38089603,
"websocket_connections": 4
}
Process information is sampled every second. The moonraker_stats field
will return up to 30 samples, each sample with the following fields:
time: Time of the sample (in seconds since the Epoch)cpu_usage: A floating point value between 0-100, representing the CPU usage of the Moonraker process.memory: Integer value representing the current amount of memory allocated in RAM (resident set size).mem_units: A string identifying the units of the value in thememoryfield. This is typically "kB", but not guaranteed.
If the system running Moonraker supports vcgencmd then Moonraker
will check the current throttled flags via vcgencmd get_throttled
and report them in the throttled_state field:
bits: An integer value that represents the bits reported byvcgencmd get_throttledflags: Descriptive flags parsed out of the bits. One or more of the following flags may be reported:- "Under-Voltage Detected"
- "Frequency Capped"
- "Currently Throttled"
- "Temperature Limit Active"
- "Previously Under-Volted"
- "Previously Frequency Capped"
- "Previously Throttled"
- "Previously Temperature Limited"
The first four flags indicate an active throttling condition,
whereas the last four indicate a previous condition (may or
may not still be active). If vcgencmd is not available
throttled_state will report null.
If the system reports CPU temp at /sys/class/thermal/thermal_zone0
then temperature will be supplied in the cpu_temp field. Otherwise
the field will be set to null.
If the system reports network statistics at /proc/net/dev then the
network field will contain network statistics. All available interfaces
will be tracked. Each interface reports the following fields:
rx_bytes: total number of bytes received over the interfacetx_bytes: total number of bytes transferred over the interfacebandwidth: estimated current bandwidth used (both rx and tx) in bytes/second
If network information is not available then the network field will
contain an empty object.
If the system reports cpu usage at /proc/stat then the system_cpu_usage
field will contain an object with cpu usage data. The cpu field of this
object reports total cpu usage, while each cpuX field is usage per core.
The websocket_connections field reports the number of active websockets
currently connected to moonraker.
Get Sudo Info

HTTP request:
POST /machine/sudo/password
Content-Type: application/json
{
"password": "linux_user_password"
}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "machine.sudo.password",
"params": {
"password": "linux_user_password"
},
"id": 7896
}
Parameters:
password: The linux user password used to grant elevated permission. This parameter must be provided.
Returns:
An object in the following format:
{
"sudo_responses": [
"Sudo password successfully set."
],
"is_restarting": false
}
sudo_responses: An array of one or more sudo responses. If there are pending sudo requests each request will provide a response.is_restarting: A boolean value indicating that a sudo request prompted Moonraker to restart its service.
This request will return an error if the supplied password is incorrect or if any pending sudo requests fail.
File Operations
Most file operations are available over both APIs, however file upload and file download are currently only available via HTTP APIs.
Moonraker organizes local directories into "roots". For example,
gcodes are located at http:\\host\server\files\gcodes\*, otherwise known
as the "gcodes" root. The following roots are available:
- gcodes
- config
- config_examples (read-only)
- docs (read-only)
Write operations (upload, delete, make directory, remove directory) are
only available on the gcodes and config roots. Note that the config root
is only available if the config_path option has been set in Moonraker's
configuration.
List available files
Walks through a directory and fetches all files. All file names include a
path relative to the specified root.
HTTP request:
GET /server/files/list?root={root_folder}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "server.files.list",
"params": {
"root": "{root_folder}"
},
"id": 4644
}
!!! tip
If the root argument is omitted the request will default to
the gcodes root.
!!! note
The gcodes root will only return files with valid gcode
extensions.
Returns: A list of objects, where each object contains file data.

}
Move a file or directory
Moves a file or directory from one location to another. The following conditions must be met for a move successful move:
- The source must exist
- The user (typically "pi") must have the appropriate file permissions
- Neither the source nor destination can be loaded by the
virtual_sdcard. If the source is a directory, it must not contain a file loaded by thevirtual_sdcard.
When specifying the source and dest, the root directory should be
prefixed. Currently the only supported roots for dest are gcodes"
and config".
This API may also be used to rename a file or directory. Be aware that an attempt to rename a directory to a directory that already exists will result in moving the source directory into the destination directory. Also be aware that renaming a file to a file that already exists will result in overwriting the existing file.

contains the path and root the item was moved from. The action field
will be move_file if the source is a file or move_dir if the source is
a directory.
Copy a file or directory
Copies a file or directory from one location to another. A successful copy has
the prerequisites as a move with one exception, a copy may complete if the
source file or directory is loaded by the virtual_sdcard. As with the move
API, the source and dest should have the root prefixed to the path.

File download
Retrieves file filename at root root. The filename must include
the relative path if it is not in the root folder.
HTTP request:
GET /server/files/{root}/{filename}
JSON-RPC request: Not Available
Returns:
The requested file
File upload
Upload a file. Currently files may be uploaded to the gcodes or config
roots, with gcodes being the default. If one wishes to upload
to a subdirectory, the path may be added to the upload's file name
(relative to the root). If the directory does not exist an error will be
returned. Alternatively, the path form argument may be set, as explained
below.
HTTP request:
POST /server/files/upload`
Content-Type: multipart/form-data
------FormBoundaryemap3PkuvKX0B3HH
Content-Disposition: form-data; name="file"; filename="myfile.gcode"
Content-Type: application/octet-stream
<binary data>
------FormBoundaryemap3PkuvKX0B3HH--
The file must be uploaded in the request's body multipart/form-data (ie:
<input type="file">). The following arguments may also be added to the
form-data:
root: The root location in which to upload the file. Currently this may begcodesorconfig. If not specified the default isgcodes.path: This argument may contain a path (relative to the root) indicating a subdirectory to which the file is written. If apathis present the server will attempt to create any subdirectories that do not exist.checksum: A SHA256 hex digest calculated by the client for the uploaded file. If this argument is supplied the server will compare it to its own checksum calculation after the upload has completed. A checksum mismatch will result in a 422 error.
Arguments available only for the gcodes root:
print: If set to "true", Klippy will attempt to start the print after uploading. Note that this value should be a string type, not boolean. This provides compatibility with OctoPrint's upload API.
JSON-RPC request: Not Available
Returns: Information about the uploaded file. Note that print_started
is only included when the supplied root is set to gcodes.

Download moonraker.log
!!! Note
Logs are now available in the logs root. Front ends should consider
presenting all available logs using "file manager" type of UI. That said,
If Moonraker has not been configured to write logs in the logs root then
this endpoint is available as a fallback.
HTTP request:
GET /server/files/moonraker.log
JSON-RPC request: Not Available
Returns:
The requested file
Authorization
The Authorization endpoints are enabled when the user has the
[authorization] component configured in moonraker.conf.
Untrusted clients must use either a JSON Web Token or an API key to access
Moonraker's HTTP APIs. JWTs should be included in the Authorization
header as a Bearer type for each HTTP request. If using an API Key it
should be included in the X-Api-Key header for each HTTP Request.
Websocket authentication can be achieved via the request itself or
post connection. Unlike HTTP requests it is not necessasry to pass a
token and/or API Key to each request. The
identify connection endpoint takes optional
access_token and api_key parameters that may be used to authentiate
a user already logged in, otherwise the login API may be used for
authentication. Websocket connections will stay authenticated until
the connection is closed or the user logs out.
!!! note
ECMAScript imposes limitations on certain requests that prohibit the
developer from modifying the HTTP headers (ie: The request to open a
websocket, "download" requests that open a dialog). In these cases
it is recommended for the developer to request a oneshot_token, then
send the result via the token query string argument in the desired
request.
!!! warning It is strongly recommended that arguments for the below APIs are passed in the request's body.

!!! Note This endpoint may be accessed by unauthorized clients. A 401 would only be returned if the refresh token is invalid.
Generate a Oneshot Token
Javascript is not capable of modifying the headers for some HTTP requests
(for example, the websocket), which is a requirement to apply JWT or API Key
authorization. To work around this clients may request a Oneshot Token and
pass it via the query string for these requests. Tokens expire in 5 seconds
and may only be used once, making them relatively safe for inclusion in the
query string.
HTTP request:
GET /access/oneshot_token
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "access.oneshot_token",
"id": 1323
}
Returns:
A temporary token that may be added to a request's query string for access to any API endpoint. The query string should be added in the form of:
?token={base32_random_token}
Retrieve information about authorization endpoints

GET /access/info
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "access.info",

"default_source": "moonraker",
"available_sources": [
"moonraker",
"ldap"
]
}
Get the Current API Key
HTTP request:
GET /access/api_key
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "access.get_api_key",
"id": 1323
}
Returns:
The current API key
Generate a New API Key
HTTP request:
POST /access/api_key
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "access.post_api_key",
"id": 1323
}
Returns:
The newly generated API key. This overwrites the previous key. Note that the API key change is applied immediately, all subsequent HTTP requests from untrusted clients must use the new key. Changing the API Key will not affect open websockets authenticated using the previous API Key.
Database APIs
The following endpoints provide access to Moonraker's lmdb database. The
database is divided into namespaces. Each client may define its own
namespace to store information. From the client's point of view, a
namespace is an object. Items in the database are accessed by providing
a namespace and a key. A key may be specified as string, where a "." is a
delimiter, to access nested fields. Alternatively the key may be specified
as an array of strings, where each string references a nested field.
This is useful for scenarios where your namespace contains keys that include
a "." character.
!!! note
Moonraker reserves the moonraker, gcode_metadata, and history
namespaces. Clients may read from these namespaces but they may not
modify them.
For example, assume the following object is stored in the "superclient" namespace:
{
"settings": {
"console": {
"enable_autocomplete": true
}
},
"theme": {
"background_color": "black"
}
}
One may access the enable_autocomplete field by supplying superclient as
the namespace argument and settings.console.enable_autocomplete or
["settings", "console", "enable_autocomplete"] as the key argument for
the request. The entire settings object could be accessed by providing
settings or ["settings"] as the key argument. The entire namespace
may be read by omitting the key argument, however as explained below it
is not possible to modify a namespace without specifying a key.
List namespaces
Lists all available namespaces.
HTTP request:
GET /server/database/list
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "server.database.list",
"id": 8694
}
Returns:
An object containing an array of namespaces in the following format:
{
"namespaces": [
"gcode_metadata",
"history",
"moonraker",
"test_namespace"
]
}
Get Database Item
Retrieves an item from a specified namespace. The key argument may be
omitted, in which case an object representing the entire namespace will
be returned in the value field. If the key is provided and does not
exist in the database an error will be returned.
HTTP request:
GET /server/database/item?namespace={namespace}&key={key}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "server.database.get_item",
"params": {
"namespace": "{namespace}",
"key": "{key}"
},
"id": 5644
}
Returns:
An object containing the requested namespace, key, and value.
{
"namespace": "moonraker",
"key": "file_manager.metadata_version",
"value": 2
}
Add Database Item
Inserts an item into the database. If the namespace does not exist
it will be created. If the key specifies a nested field, all parents
will be created if they do not exist. If the key exists it will be
overwritten with the provided value. The key parameter must be provided,
as it is not possible to assign a value directly to a namespace.
HTTP request:
POST /server/database/item?namespace={namespace}&key={key}value={value}`
!!! note
If the value is not a string type, the value argument must
provide a type hint. Alternatively,
arguments may be passed via the request body in JSON format. For
example:
POST /server/database/item
Content-Type: application/json
{
"namespace": "my_client",
"key": "settings.some_count",
"value": 100
}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "server.database.post_item",
"params": {
"namespace": "{namespace}",
"key": "{key}",
"value": 100
},
"id": 4654
}
Returns:
An object containing the inserted namespace, key, and value.
{
"namespace": "test",
"key": "settings.some_count",
"value": 9001
}
Delete Database Item
Deletes an item from a namespace at the specified key. If the key does not
exist in the namespace an error will be returned. If the deleted item results
in an empty namespace, the namespace will be removed from the database.
HTTP request:
DELETE /server/database/item?namespace={namespace}&key={key}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "server.database.delete_item",
"params": {
"namespace": "{namespace}",
"key": "{key}"
},
"id": 4654
}
Returns:
An object containing the namespace, key, and value of the
deleted item.
{
"namespace": "test",
"key": "settings.some_count",
"value": 9001
}
Job Queue APIs

Below is an explanation for each field:
busy: set to true if an update is in progress. Moonraker will not allow concurrent updates.github_rate_limit: the maximum number of github API requests the user currently is allowed. An unauthenticated user typically has 60 requests per hour.github_requests_remaining: the number of API request the user currently has remaining.github_limit_reset_time: the time when the rate limit will reset, reported as seconds since the epoch (aka Unix Time).
The moonraker, klipper packages, along with and clients configured
as applications have the following fields:
configured_type: the application type configured by the userdetected_type: the application type as detected by Moonraker.channel: the currently configured update channel. For Moonraker and Klipper this is set in the[update_manager]configuration. For clients the channel is determined by the configured typeneed_channel_update: This will be set totrueif Moonraker has detected that a channel swap is necessary (ie: the configured type does not match the detected type). The channel swap will be performed on the next update.pristine: Forzipandzip_betatypes this is set totrueif an applications source checksum matches the one generated when the app was built. This value will be set to the opposite of "dirty" for git repos. Note that a zip application can still be updated if the repo is not pristine.owner: the owner of the repo / applicationbranch: the name of the current git branch. This should typically be "master".remote_alias: the alias for the remote. This should typically be "origin".version: abbreviated version of the current repo on diskremote_version: abbreviated version of the latest available updatefull_version_string: The complete version string of the current repo.current_hash: hash of the most recent commit on diskremote_hash: hash of the most recent commit pushed to the remoteis_valid: true if installation is a valid git repo on the master branch and an "origin" set to the official remote. Forzipandzip_betatypes this will report false if Moonraker is unable to fetch the current repo state from GitHub.corrupt: Indicates that the git repo has been corrupted. When a repo is in this state it a hard recovery (ie: re-cloning the repo) is necessary. Note that the most common cause of repo corruption is removing power from the host machine without safely shutting down. Damaged storage can also lead to repo corruption.is_dirty: true if the repo has been modified. This will always be false forzipandzip_betatypes.detached: true if the repo is currently in a detached state. Forzipandzip_betatypes it is considered detached if the local release info does not match what is present on the remote.debug_enabled: True whenenable_repo_debughas been configured. This will bypass repo validation allowing detached updates, and updates from a remote/branch other than than the primary (typically origin/master).commits_behind: A list of commits behind. Up to 30 "untagged" commits will be reported. Moonraker checks the last 100 commits for tags, any commits beyond the last 30 with a tag will also be reported.git_messages: If a repo is in the "invalid" state this field will hold a list of string messages containing the output of the last failed git command. Note that it is possible for a git command to fail without providing output (for example, it may become non-responsive and time out), so it is possible for this field to be an empty list when the repo is invalid.info_tags: These are tags defined in the[update_manager client_name]configuration for each client. Client developers my define what tags, if any, users will configure. They can choose to use those tags to display information or perform an additional action after an update if necessary.recovery_url: The url Moonraker will use to re-clone the repo when a hard recovery is requested. If this reports a "?" then a hard recovery is not possible.remote_url: The url for the currently configured remote.warnings: An array of strings that describe warnings detected during repo init. These warnings describe potential issues, such as a mismatch between the detected remote and the configured remote. If theis_validfield reportsFalsethen the warnings will contain additional context.
Web clients have the following fields:
channel: channel to fetch updates fromconfigured_type: will bewebname: name of the configured clientowner: the owner of the clientversion: version of the installed client.remote_version: version of the latest release published to GitHubinfo_tags: These are tags defined in the[update_manager client_name]configuration for each client. Client developers my define what tags, if any, users will configure. They can choose to use those tags to display information or perform an additional action after an update if necessary.is_valid: A boolean that reports true if an update is possible, false if an update cannot be performed.warnings: An array of strings that describe warnings detected during repo init. These warnings describe potential issues, such as a mismatch between the detected owner and the configured owner. If theis_validfield reportsFalsethen the warnings will contain additional context.
The system package has the following fields:
package_count: the number of system packages available for updatepackage_list: an array containing the names of packages available for update
Refresh update status
Refreshes the internal update state for the requested item(s).
HTTP request:
POST /machine/update/refresh?name=klipper
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "machine.update.refresh",
"params": {

},
"id": 4644
}
Parameters:
name: (Optional) The name of the specified application. If omitted all registered applications will be refreshed.
Returns:
An object containing full update status matching the response in the status endpoint.
!!! Note This endpoint will raise 503 error under the following conditions:
- An update is in progress
- A print is in progress
- The update manager hasn't completed initialization
!!! Warning Applications should use care when calling this method as a refresh is CPU intensive and may be time consuming. Moonraker can be configured to refresh state periodically, thus it is recommended that applications avoid their own procedural implementations. Instead it is best to call this API only when a user requests a refresh.

Recover a corrupt repo
On occasion a git command may fail resulting in a repo in a
dirty or invalid state. When this happens it is possible
to recover. The name argument must specify the name of
the repo to recover, it must be of a git repo type. There are two
methods of recovery, the hard argument determines which method
is used:
hard == true: Moonraker will remove the old directory entirely. It will then attempt to recover withrsyncby restoring a backup of a recent valid repo.hard == false: Will rungit clean -f -dfollowed bygit reset --hard {remote}/{branch}. This is useful for recovering dirty repos that are valid. It is possible that this will work on an invalid repo, however it will not work on a corrupt repo.
The hard argument defaults to false.
HTTP request:
POST /machine/update/recover?name=moonraker&hard=false
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "machine.update.recover",

MQTT APIs
The following API is available when [mqtt] has been configured.
!!! Note
These requests are not available over the mqtt transport as they
are redundant. MQTT clients can publish and subscribe to
topics directly.
Publish a topic
HTTP request:
POST /server/mqtt/publish
Content-Type: application/json
{
"topic": "home/test/pub",
"payload": "hello",
"qos": 0,
"retain": false,
"timeout": 5
}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method":"server.mqtt.publish",
"params":{
"topic": "home/test/pub",
"payload": "hello",
"qos": 0,
"retain": false,
"timeout": 5
},
"id": 4564
}
Only the topic parameter is required. Below is an explanation for
each parameter:
topic: The topic to publish.payload: Payload to send with the topic. May be a boolean, float, integer, string, object, or array. All values are converted to strings prior to publishing. Objects and Arrays are JSON encoded. If omitted an empty payload is sent.qos: QOS level to use when publishing the topic. Must be an integer value from 0 to 2. If omitted the system configured default is used.retain: If set totruethe MQTT broker will retain the payload of this request. Note that only the mostly recently tagged payload is retained. When other clients first subscribe to the topic they immediately receive the retained message. The default isfalse.timeout: A float value in seconds. By default requests with QoS levels of 1 or 2 will block until the Broker acknowledges confirmation. This option applies a timeout to the request, returning a 504 error if the timeout is exceeded. Note that the topic will still be published if the QoS level is 1 or 2.
!!! tip
To clear a retained value of a topic, publish the topic with an empty
payload and retain set to true.
Returns:
The published topic:
{
"topic": "home/test/pub"
}
Subscribe to a topic
HTTP request:
POST /server/mqtt/subscribe
Content-Type: application/json
{
"topic": "home/test/sub",
"qos": 0,
"timeout": 5
}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method":"server.mqtt.subscribe",
"params":{
"topic": "home/test/sub",
"qos": 0,
"timeout": 5
},
"id": 4564
}
Only the topic parameter is required. Below is an explanation for
each paramater:
topic: The topic to subscribe. Note that wildcards may not be used.qos: QOS level to use when subscribing to the topic. Must be an integer value from 0 to 2. If omitted the system configured default is used.timeout: A float value in seconds. By default requests will block indefinitely until a response is received. This option applies a timeout to the request, returning a 504 error if the timeout is exceeded. The subscription will be removed after a timeout.
!!! note If the topic was previously published with a retained payload this request will return with the retained value.
Returns:
The subscribed topic and its payload:
{
"topic": "home/test/pub",
"payload": "test"
}
If the payload is json encodable it will be returned as an object or array. Otherwise it will be a string.
Extension APIs
Moonraker currently has limited support for 3rd party extensions. These
extensions must create a websocket connect and identify
themselves as an agent. Agents may host their own JSON-RPC methods
that other clients may call. Agents may also emit events that are
broadcast to all other websocket connections.
List Extensions
Returns a list of all available extensions. Currently Moonraker can only
be officially extended through connected agents.
HTTP request:
GET /server/extensions/list
JSON-RPC request:
{
"jsonrpc": "2.0",
"method":"server.extensions.list",
"id": 4564
}
Returns:
A list of connected agents, where each item is an object containing the agent's identity:
{
"agents": [
{
"name": "moonagent",
"version": "0.0.1",
"type": "agent",
"url": "https://github.com/arksine/moontest"
}
]
}
Call an extension method
This API may be used to call a method on a connected agent. The request effectively relays a JSON-RPC request from a client to the agent.
HTTP request:
POST /server/extensions/request
Content-Type: application/json
{
"agent": "moonagent",
"method": "moontest.hello_world",
"arguments": {"argone": true, "argtwo": 9000}
}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method":"server.extensions.request",
"params":{
"agent": "moonagent",
"method": "moontest.hello_world",
"arguments": {"argone": true, "argtwo": 9000}
},
"id": 4564
}
Parameters:
agent: The name of the agent. This parameter is required.method: The name of the method to call on the agent. Agents determine the method names they expose. This parameter is required.arguments: This parameter is optional, depending on if the method being called takes parameters. This should be either an array of positional arguments or an object of keyword arguments.
Returns:
The result returned by the JSON-RPC call to the agent. This can be any JSON value as determined by the agent.
Send an agent event
!!! Note
This API is only available to websocket connections that have
identified themselves as an agent type.
HTTP Request: Not Available
JSON-RPC request:
{
"jsonrpc": "2.0",
"method":"connection.send_event",
"params":{
"event": "my_event",
"data": {"my_arg": "optional data"}
}
}
Parameters:
event: The name of the event. This may be any name as determined by the agent, with the exception of the reserved names noted below.data: Optional supplemental data sent with the event. This can be any JSON value.
!!! Note
The connected and disconnected events are reserved for use
by Moonraker.
Returns:
ok if an id was present in the request, otherwise no response is
returned. Once received, Moonraker will broadcast this event via
the agent event notification to all other connections.
Debug APIs
The APIs in this section are available when Moonraker the debug argument
(-g) has been supplied via the command line. Some API may also depend
on Moonraker's configuration, ie: an optional component may choose to
register a debug API.
!!! Warning Debug APIs may expose security vulnerabilities. They should only be enabled by developers on secured machines.
List Database Namespaces (debug)
Debug version of List Namespaces. Return value includes namespaces exlusively reserved for Moonraker. Only availble when Moonraker's debug features are enabled.
HTTP request:
GET /debug/database/list
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "debug.database.list",
"id": 8694
}
Get Database Item (debug)
Debug version of Get Database Item. Keys within protected and forbidden namespaces are accessible. Only availble when Moonraker's debug features are enabled.

JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "debug.database.get_item",
"params": {
"namespace": "{namespace}",
"key": "{key}"
},
"id": 5644
}
Add Database Item (debug)
Debug version of Add Database Item. Keys within protected and forbidden namespaces may be added. Only availble when Moonraker's debug features are enabled.
!!! Warning This endpoint should be used for testing/debugging purposes only. Modifying protected namespaces outside of Moonraker can result in broken functionality and is not supported for production environments. Issues opened with reports/queries related to this endpoint will be redirected to this documentation and closed.

"jsonrpc": "2.0",
"method": "debug.database.post_item",
"params": {
"namespace": "{namespace}",
"key": "{key}",
"value": 100
},
"id": 4654
}
Delete Database Item (debug)
Debug version of Delete Database Item. Keys within protected and forbidden namespaces may be removed. Only availble when Moonraker's debug features are enabled.
!!! Warning This endpoint should be used for testing/debugging purposes only. Modifying protected namespaces outside of Moonraker can result in broken functionality and is not supported for production environments. Issues opened with reports/queries related to this endpoint will be redirected to this documentation and closed.
HTTP request:
DELETE /debug/database/item?namespace={namespace}&key={key}
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "debug.database.delete_item",
"params": {
"namespace": "{namespace}",
"key": "{key}"
},
"id": 4654
}
Test a notifier (debug)
You can trigger a notifier manually using this endpoint.
HTTP request:
POST /debug/notifiers/test?name=notifier_name
JSON-RPC request:
{
"jsonrpc": "2.0",
"method": "debug.notifiers.test",
"params": {
"name": "notifier_name"
},
"id": 4654
}
Parameters:
name: The name of the notifier to test.
Returns: Test results in the following format
{
"status": "success",
"stats": {
"print_duration": 0.0,
"total_duration": 0.0,
"filament_used": 0.0,
"filename": "notifier_test.gcode",
"state": "standby",
"message": ""
}
}
Websocket notifications
Printer generated events are sent over the websocket as JSON-RPC 2.0 notifications. These notifications are sent to all connected clients in the following format:
{
"jsonrpc": "2.0",
"method": "{event method name}"
}
OR
{
"jsonrpc": "2.0",
"method": "{event method name}",
"params": [<event parameter>]
}
If a notification has parameters, the params value will always be
wrapped in an array as directed by the JSON-RPC standard. Currently
all notifications available are broadcast with either no parameters
or a single parameter.
Gcode Response
All of Klippy's gcode responses are forwarded over the websocket. They arrive as a "gcode_response" notification:
{
"jsonrpc": "2.0",
"method": "notify_gcode_response",
"params": ["response message"]
}
Subscriptions
Status Subscriptions arrive as a "notify_status_update" notification:
{
"jsonrpc": "2.0",
"method": "notify_status_update",
"params": [{<status object>}, <eventtime>]
}
The structure of the status object is identical to the structure that is
returned from an object query's
status field.
The eventtime is a timestamp generated by Klipper when
the update was originally pushed. This timestamp is a float value,
relative to Klipper's monotonic clock.
Klippy Ready
Notify clients when Klippy has reported a ready state
{
"jsonrpc": "2.0",
"method": "notify_klippy_ready"
}
Klippy Shutdown
Notify clients when Klippy has reported a shutdown state
{
"jsonrpc": "2.0",
"method": "notify_klippy_shutdown"
}
Klippy Disconnected
Notify clients when Moonraker's connection to Klippy has terminated
{
"jsonrpc": "2.0",
"method": "notify_klippy_disconnected"
}
File List Changed
When a client makes a change to a file or directory in a registered
root (via upload, delete, move, etc) a notification is broadcast
to alert all connected clients of the change:
{
"jsonrpc": "2.0",
"method": "notify_filelist_changed",
"params": [
{
"action": "{action}",
"item": {
"path": "{file or directory path relative to root}",
"root": "{root}",
"size": 46458,
"modified": 545465,
"permissions": "rw"
},
"source_item": {
"path": "{file or directory path relative to root}",
"root": "{root_name}"
}
}
]
}
!!! Note
The source_item field is only present for move_file and
move_dir actions.
The action field will be set to one of the following values:
create_filecreate_dirdelete_filedelete_dirmove_filemove_dirmodify_fileroot_update
Most of the above actions are self explanatory. The root_update
notification is sent when a root folder has changed its location.
This should be a rare event as folders are now managed in using the
data folder structure.
Notifications are bundled where applicable. For example, when a
directory containing children is deleted a single delete_dir notification
is pushed. Likewise, when a directory is moved or copied, a single
move_dir or create_dir notification is pushed. Children that are
moved, copied, or deleted as a result of a parent's action will
not receive individual notifications.
Update Manager Response
The update manager will send asynchronous messages to the client during an update:
{
"jsonrpc": "2.0",
"method": "notify_update_response",
"params": [
{
"application": "{app_name}",
"proc_id": 446461,
"message": "Update Response Message",
"complete": false
}
]
}
The fields reported in the response are as follows:
- The
applicationfield contains the name of application currently being updated. Generally this will be either "moonraker", "klipper", "system", or "client". - The
proc_idfield contains a unique id associated with the current update process. This id is generated for each update request. - The
messagefield contains an asynchronous message sent during the update process. - The
completefield is set to true on the final message sent during an update, indicating that the update completed successfully. Otherwise it will be false.
Update Manager Refreshed
The update manager periodically auto refreshes the state of each application it is tracking. After an auto refresh has completed the following notification is broadcast:
{
"jsonrpc": "2.0",
"method": "notify_update_refreshed",
"params": [{update_info}]}
Where update_info is an object that matches the response from an
update status request.
CPU Throttled
If the system supports throttled CPU monitoring Moonraker will send the following notification when it detects a change to the current throttled state:
{
"jsonrpc": "2.0",
"method": "notify_cpu_throttled",
"params": [{throttled_state}]
}
Where throttled_state is an object that matches the throttled_state field
in the response from a Moonraker process stats
request. It is possible for clients to receive this notification multiple times
if the system repeatedly transitions between an active and inactive throttled
condition.
Moonraker Process Statistic Update
Moonraker will emit the following notification each time it samples its process statistics:
{
"jsonrpc": "2.0",
"method": "notify_proc_stat_update",
"params": [{
"moonraker_stats": {
"time": 1615837812.0894408,
"cpu_usage": 1.99,
"memory": 23636,
"mem_units": "kB"
},
"cpu_temp": 44.008,
"network": {
"lo": {
"rx_bytes": 114555457,
"tx_bytes": 114555457,
"bandwidth": 2911.49
},
"wlan0": {
"rx_bytes": 48773134,
"tx_bytes": 115035939,
"bandwidth": 3458.77
}
},
"system_cpu_usage": {
"cpu": 2.53,
"cpu0": 3.03,
"cpu1": 5.1,
"cpu2": 1.02,
"cpu3": 1
},
"websocket_connections": 2
}]
}
As with the proc_stats request the cpu_temp
field will be set to null if the host machine does not support retrieving CPU
temperatures at /sys/class/thermal/thermal_zone0.
History Changed
If the [history] module is enabled the following notification is sent when
a job is added or finished:
{
"jsonrpc": "2.0",
"method": "notify_history_changed",
"params": [
{
"action": "added",
"job": <job object>
}
]
}
The action field may be added or finished. The job field contains
an object matches the one returned when requesting
job data.
Authorized User Created
If the [authorization] module is enabled the following notification is
sent when a new user is created:
{
"jsonrpc": "2.0",
"method": "notify_user_created",
"params": [
{
"username": "<username>"
}
]
}
Authorized User Deleted
If the [authorization] module is enabled the following notification is
sent when an existing user is deleted.
{
"jsonrpc": "2.0",
"method": "notify_user_deleted",
"params": [
{
"username": "<username>"
}
]
}
Authorized User Logged Out
If the [authorization] module is enabled the following notification is
sent when an existing user is logged out.
{
"jsonrpc": "2.0",
"method": "notify_user_logged_out",
"params": [
{
"username": "<username>"
}
]
}
Service State Changed
Moonraker monitors the state of systemd services it is authorized to track. When the state of a service changes the following notification is sent:
{
"jsonrpc": "2.0",
"method": "notify_service_state_changed",
"params": [
{
"klipper": {
"active_state": "inactive",
"sub_state": "dead"
}
}
]
}
The example above shows that the klipper service has changed to inactive.
Job Queue Changed
Moonraker will send a job_queue_changed notification when a change is
detected to the queue state or the queue itself:
{
"jsonrpc": "2.0",
"method": "notify_job_queue_changed",
"params": [
{
"action": "state_changed",
"updated_queue": null,
"queue_state": "paused"
}
]
}
The object sent with the notification contains the following fields:
action: The action taken to the queue which led to the notification. Will be a string set to one of the following values:state_changed: The queue state has changedjobs_added: One or more jobs were added to the queuejobs_removed: One or more jobs were removed from the queuejob_loaded: A job was popped off the queue and successfully started
updated_queue: If the queue itself is changed this will be a list containing each item in the queue. If the queue has not changed this will benull.queue_state: The current queue state
Button Event
Moonraker [button] components may be configured to emit websocket
notifications.
{
"jsonrpc": "2.0",
"method": "notify_button_event",
"params": [
{
"name": "my_button",
"type": "gpio",
"event": {
"elapsed_time": 0.09323832602240145,
"received_time": 698614.214597004,
"render_time": 698614.214728513,
"pressed": false
},
"aux": null
}
]
}
The params array will always contain a single object with the following
fields:
name: The name of the configured buttontype: The button type, currently this will always begpioevent: An object with details about the button event, containing the following fields:elapsed_time: The time elapsed (in seconds) since the last detected button eventreceived_time: The time the event was detected according to asyncio's monotonic clock. Note that this is not in "unix time".render_time: The time the template was rendered (began execution) according to asyncio's monotonic clock. It is possible execution of an event may be delayed well beyond thereceived_time.pressed: A boolean value to indicate if the button is currently pressed.
aux: This is an optional field where the button may specify any json encodable value. Clients may suggest a specific button configuration that includes details about the event. If no aux parameter is specified in the configuration this will be anullvalue.
Announcement update event
Moonraker will emit the notify_announcement_update notification when
a announcement entries are added or removed:
{
"jsonrpc": "2.0",
"method": "notify_announcement_update",
"params": [
{
"entries": [

}
The params array will contain an object with the entry_id of the
announcement that is no longer dismissed.
Sudo alert event
Moonraker will emit the notify_sudo_alert notification when
a component has requested sudo access. The event is also emitted
when a sudo request has been granted.
{
"jsonrpc": "2.0",
"method": "notify_sudo_alert",
"params": [
{
"sudo_requested": true,
"sudo_messages": [
"Sudo password required to update Moonraker's systemd service."
]
}
]
}
The params array contains an object with the following fields:
sudo_requested: Returns true if Moonraker is currently requesting sudo access.request_messages: An array of strings, each string describing a pending sudo request. The array will be empty if no sudo requests are pending.
Webcams changed event
Moonraker will emit the notify_webcams_changed event when a configured
webcam is added, removed, or updated.
{
"jsonrpc": "2.0",
"method": "notify_webcams_changed",
"params": [
{
"webcams": [
{
"name": "tc2",
"location": "printer",
"service": "mjpegstreamer",
"enabled": true,
"icon": "mdiWebcam",
"target_fps": 15,
"target_fps_idle": 5,
"stream_url": "http://printer.lan/webcam?action=stream",
"snapshot_url": "http://printer.lan/webcam?action=snapshot",
"flip_horizontal": false,
"flip_vertical": false,
"rotation": 0,
"aspect_ratio": "4:3",
"extra_data": {},
"source": "database"
},
{
"name": "TestCam",
"location": "printer",
"service": "mjpegstreamer",
"enabled": true,
"icon": "mdiWebcam",
"target_fps": 15,
"target_fps_idle": 5,
"stream_url": "/webcam/?action=stream",
"snapshot_url": "/webcam/?action=snapshot",
"flip_horizontal": false,
"flip_vertical": false,
"rotation": 0,
"aspect_ratio": "4:3",
"extra_data": {},
"source": "database"
}
]
}
]
}
The webcams field contans an array of objects like those returned by the
list webcams API.
Agent Events
Moonraker will emit the notify_agent_event notification when it
an agent event is received.
{
"jsonrpc": "2.0",
"method": "notify_agent_event",
"params": [
{
"agent": "moonagent",
"event": "connected",
"data": {
"name": "moonagent",
"version": "0.0.1",
"type": "agent",
"url": "https://github.com/arksine/moontest"
}
}
]
}
When an agent connects, all connections will receive a connected event
for that agent, with its identity info in the data field. When an agent
disconnects clients will receive a disconnected event with the data field
omitted. All other events are determined by the agent, where each event may
or may not include optional data.
Sensor Events
Moonraker will emit a sensors:sensor_update notification when a measurement
from at least one monitored sensor changes.
{
"jsonrpc": "2.0",
"method": "sensors:sensor_update",
"params": [
{
"sensor1": {
"humidity": 28.9,
"temperature": 22.4
}
}
]
}
When a sensor reading changes, all connections will receive a
sensors:sensor_update event where the params contains a data struct
with the sensor id as the key and the sensors letest measurements as value
struct.
Appendix
Websocket setup
The websocket is located at ws://host:port/websocket, for example:
var s = new WebSocket("ws://" + location.host + "/websocket");
!!! tip A client using API Key authorization may request a oneshot token, applying the result to the websocket request's query string:
ws://host:port/websocket?token={32 character base32 string}
The following startup sequence is recommended for clients which make use of the websocket:
- Attempt to connect to
/websocketuntil successful using a timer-like mechanism - Once connected, query
/server/info(orserver.info) for the ready status.- If the response returns an error (such as 404) then either the client
is not authorized or Moonraker is not running. Direct the user to
SSH into the machine and check
/tmp/moonraker.log. - If the response returns success, check the result's
klippy_statefield:klippy_state == "ready": you may proceed to request status of printer objects make subscriptions, get the file list, etc.klippy_state == "error": Klippy has experienced an error starting upklippy_state == "shutdown": Klippy is in a shutdown state.klippy_state == "startup": re-request/server/infoin 2 seconds.- If
errororshutdownis detected it might be wise to prompt the user. You can get a description from thestate_messagefield of a/printer/inforequest.
- If
- If the response returns an error (such as 404) then either the client
is not authorized or Moonraker is not running. Direct the user to
SSH into the machine and check
- Repeat step 2 until Klipper reports ready.
- Clients should watch for the
notify_klippy_disconnectedevent. If received then Klippy has either been stopped or restarted. In this state the client should repeat the steps above to determine when klippy is ready.
Basic Print Status
An advanced client will likely use subscriptions and notifications to interact with Moonraker, however simple clients such as home automation software and embedded devices (ie: ESP32) may only wish to monitor the status of a print. Below is a high level walkthrough for receiving print state via polling.
-
Set up a timer to poll at the desired interval. Depending on your use case, 1 to 2 seconds is recommended.
-
On each cycle, issue the following request:
GET http://host/printer/objects/query?webhooks&virtual_sdcard&print_statsOr via JSON-RPC 2.0:
{ "jsonrpc": "2.0", "method": "printer.objects.query", "params": { "objects": { "webhooks": null, "virtual_sdcard": null, "print_stats": null } }, "id": 5664 } -
If the request returns an error or the returned
result.statusis an empty object, then this is an indication that Klippy either experienced an error or it is not properly configured. Each queried object should be available inresult.status. The client should check to make sure that all objects are received before proceeding. -
Inspect
webhooks.ready. If the value is notreadythe printer is not available.webhooks.messagecontains a message pertaining to the current state. -
If the printer is ready, inspect
print_stats.state. It may be one of the following values: -standby: No print in progress -printing: The printer is currently printing -paused: A print in progress has been paused -error: The print exited with an error.print_stats.messagecontains a related error message -complete: The last print has completed -
If
print_stats.stateis notstandbythenprint_stats.filenamewill report the name of the currently loaded file. -
print_stats.filenamecan be used to fetch file metadata. It is only necessary to fetch metadata once per print.GET http://host/server/files/metadata?filename=<filename>Or via JSON-RPC 2.0:
{ "jsonrpc": "2.0", "method": "server.files.metadata", "params": { "filename": "{filename}" }, "id": 5643 }If metadata extraction failed then this request will return an error. Some metadata fields are only populated for specific slicers, and unsupported slicers will only return the size and modified date.
-
There are multiple ways to calculate the ETA, this example will use file progress, as it is possible calculate the ETA with or without metadata.
-
If
metadata.estimated_timeis available, the eta calculation can be done as:// assume "result" is the response from the status query let vsd = result.status.virtual_sdcard; let prog_time = vsd.progress * metadata.estimated_time; let eta = metadata.estimated_time - prog_timeAlternatively, one can simply subtract the print duration from the estimated time:
// assume "result" is the response from the status query let pstats = result.status.print_status; let eta = metadata.estimated_time - pstats.print_duration; if (eta < 0) eta = 0; -
If no metadata is available, print duration and progress can be used to calculate the ETA:
// assume "result" is the response from the status query let vsd = result.status.virtual_sdcard; let pstats = result.status.print_stats; let total_time = pstats.print_duration / vsd.progress; let eta = total_time - pstats.print_duration;
-
-
It is possible to query additional objects if a client wishes to display more information (ie: temperatures). See the Printer Objects documentation for details.
Bed Mesh Coordinates
The Bed Mesh printer object may be used to generate three dimensional coordinates of a probed area (or mesh). Below is an example (in javascript) of how to transform the data received from a bed_mesh object query into an array of 3D coordinates.
// assume that we have executed an object query for bed_mesh and have the
// result. This example generates 3D coordinates for the probed matrix,
// however it would work with the mesh matrix as well
function process_mesh(result) {
let bed_mesh = result.status.bed_mesh
let matrix = bed_mesh.probed_matrix;
if (!(matrix instanceof Array) || matrix.length < 3 ||
!(matrix[0] instanceof Array) || matrix[0].length < 3)
// make sure that the matrix is valid
return;
let coordinates = [];
let x_distance = (bed_mesh.mesh_max[0] - bed_mesh.mesh_min[0]) /
(matrix[0].length - 1);
let y_distance = (bed_mesh.mesh_max[1] - bed_mesh.mesh_min[1]) /
(matrix.length - 1);
let x_idx = 0;
let y_idx = 0;
for (const x_axis of matrix) {
x_idx = 0;
let y_coord = bed_mesh.mesh_min[1] + (y_idx * y_distance);
for (const z_coord of x_axis) {
let x_coord = bed_mesh.mesh_min[0] + (x_idx * x_distance);
x_idx++;
coordinates.push([x_coord, y_coord, z_coord]);
}
y_idx++;
}
}
// Use the array of coordinates visualize the probed area
// or mesh..
Converting to Unix Time
Some of Moonraker's APIs return a date represented in Unix time. Most languages have functionality built in to convert Unix time to a workable object or string. For example, in JavaScript one might do something like the following:
for (let resp of result.gcode_store) {
let date = new Date(resp.time * 1000);
// Do something with date and resp.message ...
}
Announcements
Moonraker announcements are effectively push notifications that can be used to notify users of important information related the development and status of software in the Klipper ecosystem. This section will provide an overview of how the announcement system works, how to set up a dev environment, and provide recommendations on client implementation.
How announcements work
Moonraker announcements are GitHub issues tagged with the announcement
label. GitHub repos may registered with
moonlight, which is responsible
for generating RSS feeds from GitHub issues using GitHub's REST API. These
RSS feeds are hosted on GitHub Pages, for example Moonraker's feed may be found
here. By
centralizing GitHub API queries in moonlight we are able to poll multiple
repos without running into API rate limit issues. Moonlight has has a workflow
that checks all registered repos for new announcements every 30 minutes. In
theory it would be able to check for announcements in up to 500 repos before
exceeding GitHub's API rate limit.
Moonraker's [announcements] component will always check the klipper and
moonraker RSS feeds. It is possible to configure additional RSS feeds by
adding them to the subscriptions option. The component will poll configured
feeds every 30 minutes, resulting in maximum of 1 hour for new announcements
to reach all users.
When new issues are tagged with announcement these entries will be parsed
and added to the RSS feeds. When the issue is closed they will be removed from
the corresponding feed. Moonlight will fetch up to 20 announcements for each
feed, if a repo goes over this limit older announcements will be removed.
!!! Note It is also possible for Moonraker to generate announcements itself. For example, if a Moonraker component needs user feedback it may generate an announcement and notify all connected clients. From a client's perspective there is no need to treat announcements differently than any other announcement.
Setting up the dev environment
Moonraker provides configuration to parse announcements from a local folder so that it is possible to manually add and remove entries, allowing client developers to perform integration tests:
# moonraker.conf
[announcements]
dev_mode: True
With dev_mode enabled, Moonraker will look formoonraker.xml and
klipper.xml in the following folder:
~/moonraker/.devel/announcement_xml
If moonraker is not installed in the home folder then substitute ~
for the parent folder location. This folder is in a hardcoded location
to so as not to expose users to vulnerabilities associated with parsing XML.
It is possible to configure Moonraker to search for your own feeds:
# moonraker.conf
[announcements]
subscription:
my_project
dev_mode: True
The above configuration would look for my_project.xml in addition to
klipper.xml and moonraker.xml. The developer may manually create
the xml feeds or they may clone moonlight and leverage its script
to generate a feed from issues created on their test repo. When local
feeds have been modified one may call the update announcements API to have Moonraker fetch the updates and add/remove
entries.
RSS file structure
Moonlight generates RSS feeds in XML format. Below is an example generated from moonlight's own issue tracker:
<?xml version='1.0' encoding='utf-8'?>
<rss version="2.0" xmlns:moonlight="https://arksine.github.io/moonlight">
<channel>
<title>arksine/moonlight</title>

</rss>
Each xml file may contain only one <rss> element, and each <rss> element
may contain only one channel. All items must be present aside from
moonlight:configHash, which is used by the workflow to detect changes to
moonlight's configuration. Most elements are self explanatory, developers will
be most interested in adding and removing <item> elements, as these are
the basis for entries in Moonraker's announcement database.
Generating announcements from your own repo
As mentioned previously, its possible to clone moonlight and use its rss script to generate announcements from issues in your repo:
cd ~
git clone https://github.com/arksine/moonlight
cd moonlight
virtualenv -p /usr/bin/python3 .venv
source .venv/bin/activate
pip install httpx[http2]
deactivate
To add your repo edit ~/moonlight/src/config.json:
{
"moonraker": {
"repo_owner": "Arksine",
"repo_name": "moonraker",
"description": "API Host For Klipper",
"authorized_creators": ["Arksine"]
},
"klipper": {
"repo_owner": "Klipper3d",
"repo_name": "klipper",
"description": "A 3D Printer Firmware",
"authorized_creators": ["KevinOConnor"]
},
// Add your test repo info here. It should contain
// fields matching those in "moonraker" and "klipper"
// shown above.
}
Once your repo is added, create one or more issues on your GitHub
repo tagged with the announcement label. Add the critical label to
one if you wish to test high priority announcements. You may need to
create these labels in your repo before they can be added.
Now we can use moonlight to generate the xml files:
cd ~/moonlight
source .venv/bin/activate
src/update_rss.py
deactivate
After the script has run it will generate the configured RSS feeds
and store them in ~/moonlight/assets. If using this method it may
be useful to create a symbolic link to it in Moonraker's devel folder:
cd ~/moonraker
mkdir .devel
cd .devel
ln -s ~/moonlight/assets announcement_xml
If you haven't done so, configure Moonraker to subscribe to your feed and restart the Moonraker service. Otherwise you may call the announcement update API to have Moonraker parse the announcements from your test feed.
Implementation details and recommendations
When Moonraker detects a change to one or more feeds it will fire the announcement update notification. It is also possible to query the API for announcements. Both the notification and the API return a list of announcement entries, where each entry is an object containing the following fields:
entry_id: A unique ID derived for each entry. Typically this is in the form of{owner}/{repo}/issue/{issue number}.url: The url to the full announcement. This is generally a link to an issue on GitHub.title: Announcement title, will match the title of the issue on GitHub.description: The first paragraph of the announcement. Anything over 512 characters will be truncated.priority: Can benormalorhigh. It is recommended that clients immediately alert the user when one or morehighpriority announcments are present. Issued tagged with thecriticallabel will be assigned ahighpriority.date: The announcement creation date in unix time.dismissed: If set totruethis announcement has been previously dismisseddate_dismissed: The date the announcement was dismissed in unix time. If the announcement has not been dismissed this value isnull.dismiss_wake: If the announcement was dismissed with awake_timespecified this is the time (in unix time) at which thedismissedstate will revert. If the announcement is not dismissed or dismissed indefinitely this value will benull.source: The source from which the announcement was generated. Can bemoonlightorinternal.feed: The RSS feed for moonlight announcements. For example, this could beMoonrakerorKlipper. If the announcement was generated internally this should match the name of the component that generated the announcement.
When a client first connects to Moonraker it is recommended that the list announcements API is called to retrieve the current list of entries. A client may then watch for the announcement update and announcement dismissed notifications and update the UI accordingly.
Client devs should decide how they want to present announcements to users. They could be treated as any other notification, for example a client
may have a notification icon that shows the current number of unread
announcements. Clients can mark an announcement as read by calling
the dismiss announcement API. Any announcement
entry with dismissed = true should be considered read.
When a high priority announcement is detected it is recommended that
clients present the announcement in a format that is immediately visible
to the user. That said, it may be wise to allow users to opt out of
this behavior via configuration.
!!! Note
If an announcement is dismissed, closed, then reopened the
dismissed flag will reset to false. This is expected behavior
as announcements are pruned from the database when they are no
longer present in feeds. It isn't valid for repo maintaners
to re-open a closed announcement. That said, its fine to close
and re-open issues during development and testing using repos
that are not yet registered with moonlight.
