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.

Browse Requests

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.
