# Scrobbling

In order to scrobble from a wide selection of clients, you can use Maloja's standard-compliant APIs with the following settings:

GNU FM |  
------ | ---------
Gnukebox URL | Your Maloja URL followed by `/apis/audioscrobbler`
Username | Doesn't matter
Password | Any of your API keys

ListenBrainz |  
------ | ---------
API URL | Your Maloja URL followed by `/apis/listenbrainz`
Username | Doesn't matter
Auth Token | Any of your API keys

Audioscrobbler v1.2 |  
------ | ---------
Server URL | Your Maloja URL followed by `/apis/audioscrobbler_legacy`
Username | Doesn't matter
Password | Any of your API keys

Note that this is the base URL - some scrobblers ask you for the full endpoint instead.

# API Documentation

The native Maloja API is reachable at `/apis/mlj_1`. Endpoints are listed on `/api_explorer`.

All endpoints return JSON data. POST request can be made with query string or form data arguments, but this is discouraged - JSON should be used whenever possible.

No application should ever rely on the non-existence of fields in the JSON data - i.e., additional fields can be added at any time without this being considered a breaking change. Existing fields should usually not be removed or changed, but it is always a good idea to add basic handling for missing fields.

## General Structure

Most endpoints follow this structure:

| Key | Type | Description |
| --- | --- | --- |
| `status` | String | Status of the request. Can be `success`, `ok`, `error`, `failure`, `no_operation` |
| `error` | Mapping | Details about the error if one occured. |
| `warnings` | List | Any warnings that did not result in failure, but should be noted. Field is omitted if there are no warnings! |
| `desc` | String | Human-readable feedback. This can be shown directly to the user if desired. |

Both errors and warnings have the following structure:


| Key | Type | Description |
| --- | --- | --- |
| `type` | String | Name of the error or warning type |
| `value` | varies | Specific data for this error or warning instance |
| `desc` | String | Human-readable error or warning description. This can be shown directly to the user if desired. |


## Entity Structure

Whenever a list of entities is returned, they have the following fields:
