## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability musicbrainz-release-group-search-via-suverse-proxy-a373bef6 -d '<json body>'
```

Example prompt: Can you search MusicBrainz for release groups matching 'Rumours' and tell me the MBID, primary type, and artist credit for the top results?

## When to prefer this

Choose this endpoint when you need to resolve a music album, single, or EP title to its canonical MusicBrainz entry (MBID and metadata) without requiring an API key. Ideal for enriching music catalogs, verifying release identity, or linking internal records to the open MusicBrainz database. Prefer it over direct MusicBrainz API calls when you want a proxied, keyless, agent-friendly interface.

## Known failure modes

- No matches found for the provided title — returns empty result set
- MusicBrainz upstream rate limiting or downtime causes request failure
- Ambiguous titles may return many loosely matched results requiring further filtering
- Proxy service unavailable returns HTTP error
- Input body missing required fields returns validation error

## How this service works

Search MusicBrainz for release groups (albums, singles, EPs) by title. Returns matches with title, primary-type, artist credit and MBID. Keyless (sends a User-Agent). Useful for finding canonical album entries in the open music database.

## Output

Returns a list of matching release group entries from MusicBrainz, each including the release group title, primary type (Album, Single, EP, etc.), artist credit name(s), and the MusicBrainz ID (MBID) for canonical referencing.
