The main web service is the XML Web Service. This page is about the (beta) JSON format of that web service. For shared documentation, like the available inc= parameters, do follow the info at the XML web service docs. To get a JSON response from the web service, you can either set the Accept header to "application/json" or add fmt=json to the query string (if both are set, fmt= takes precedence).

Beta

WARNING: This web service is available on the production server (musicbrainz.org/ws/2/) and mostly stable, but is still considered a beta, and while we do our best to avoid breaking changes, we may eventually need to make some before officially marking it as stable. If you find any issues, don't hesitate to open a ticket or contact us on IRC.

Lookup requests

Below you'll find one example of a request for each entity type, to get an idea of the data you'll get back and its formatting. Some of the responses below have some fields omitted to keep the examples shorter (additional aliases, part of the release data); in the actual response the data will obviously be included.

Event

For events, you'll generally want to include at least artist-rels (for performers) and place-rels (for location), as in the example below.

Work

For works, you'll generally want to include at least artist-rels (for writers), as in the example below.

Browse Requests

Browse requests are a direct lookup of all the entities directly linked to another entity. You can see more info about what types you can browse each entity type by if you check the documentation for XML browse requests (most of the documentation applies as-is to the JSON version of the web service).

Browse requests return a top-level object with offset and count properties to help with paging, and a property for the requested entity. Unless you set a limit (see example below) you will get 25 results per page.

The key for the entity property will be the English plural of the entity name, so: areas, artists, events, instruments, labels, places, recordings, releases, release-groups, series or works.

Browse requests are not currently available for genres.

Request: http://musicbrainz.org/ws/2/release?label=47e718e1-7ee4-460c-b1cc-1192a841c6e5&offset=12&limit=2&fmt=json

    ],

Relationships

You can request relationships with the appropriate includes:

  • area-rels
  • artist-rels
  • event-rels
  • instrument-rels
  • label-rels
  • place-rels
  • recording-rels
  • release-rels
  • release-group-rels
  • series-rels
  • url-rels
  • work-rels

These will load relationships between the requested entity and the specific entity type. For example, if you request "work-rels" when looking up an artist, you'll get all the relationships between this artist and any works, and if you request "artist-rels" you'll get the relationships between this artist and any other artists. As such, keep in mind requesting "artist-rels" for an artist, "release-rels" for a release, etc. will not load all the relationships for the entity, just the ones to other entities of the same type.

You can find examples of relationship requests above, under Event and Work.

in a release request, you might also be interested on relationships for the recordings linked to the release, or even for the works linked to those recordings (for example, to find out who played guitar on a specific track or who wrote the lyrics for the song being performed). Similarly, for a recording request, you might want to get the relationships for any linked works. There are two additional includes for this:

  • recording-level-rels
  • work-level-rels

Keep in mind these just act as switches. If you request work-level-rels for a recording, you will still need to request work-rels (to get the relationship from the recording to the work in the first place) and any other relationship types you want to see (for example, artist-rels if you want to see work-artist relationships). See the example below for a one-track classical release with both performers (recording level relationships) and composer (work level relationship).
