  title: MusicBrainz Web Service v2 Areas Series API
  version: '2.0'
  description: 'The MusicBrainz Web Service v2 is the free public REST API to the MusicBrainz open music encyclopedia,

    operated by the MetaBrainz Foundation (a US 501(c)(3) non-profit).


    The API supports three primary access patterns over twelve core entity types

    (artist, release, release-group, recording, work, label, place, area, event, instrument, series, url, genre):


    - **Lookup** — fetch one entity by its MBID with configurable sub-resource includes.

    - **Browse** — list entities linked to a given parent entity, with pagination.

    - **Search** — full Lucene query syntax across the indexed catalog.


    Non-MBID lookups are available for ISRC (recordings), ISWC (works), DiscID (releases), and URL.


    Responses are returned in MMD-2 XML by default or JSON via the `fmt=json` query parameter.


    The API enforces a strict rate limit of **one request per IP per second** and requires a meaningful

    **User-Agent** header on every request (e.g. `MyApp/1.0.0 ( contact@example.com )`).

    Submission and user-specific endpoints require HTTP Basic or OAuth 2.0 authentication.
