MusicBrainz API/Examples

From MusicBrainz Wiki
Jump to navigationJump to search

This document describes the proposed JSON output, using example queries and the responses I am proposing. Getting a JSON response will require setting the Accept header to "application/json".

Some notable differences compared to the JSON response currently used internally by the search server:

  1. all "-list" elements are replaced with javascript arrays, using an english plural as the key. So { "tag-list": { "tag": [ ... ] } } becomes { "tags": [ ... ] }.
  2. the "name-credit" key inside an "artist-credit" is removed.

Some of the responses below have some fields omitted to keep the examples shorter, in the actual webservice obviously this data will be included.
