What you get#
Onekey exposes MusicBrainz as 16 endpoints behind one API key: 7 endpoints return one record (data is an object) and 9 endpoints return a list (data is an array). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for MusicBrainz also works for the rest of the music & audio category.

-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from MusicBrainz, with the same names as on every other platform. The count is how many of its 16 mapped endpoints return the field; a field the source lacks is null, never missing. 2 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
| Field | Type | Endpoints |
|---|---|---|
entity.id | string | 16 |
entity.name | string | 16 |
entity.type | string | 11 |
author.displayName | string | 8 |
entity.releaseDate | ISO 8601 date | 8 |
entity.country | string | 7 |
event.startDate | ISO 8601 date | 4 |
entity.status | string | 3 |
listing.barcode | string | 3 |
entity.language | string | 2 |
The full schema is in Unified schema.
