# MusicBrainz Recording Search via Suverse Proxy

> MusicBrainz Recording Search via Suverse Proxy is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.06/call, status unknown (last checked 2026-09-14).

Searches MusicBrainz for audio recordings (tracks) by title, returning canonical matches with title, duration, artist credit, and MBID.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-recording-search-via-suverse-proxy-f3275a56 -d '<json body>'
```

Example prompt: Can you find the MusicBrainz recording entry for 'Bohemian Rhapsody' by Queen — I need its MBID, track length, and artist credit?

## When to prefer this

Use this endpoint when you need to resolve a human-readable song title to a canonical MusicBrainz Recording ID (MBID) or retrieve structured track metadata (duration, artist credit) without needing an API key. Prefer this over direct MusicBrainz API calls when operating in a keyless, agent-friendly paid-per-call context via the x402 protocol.

## Known failure modes

- No matches found for obscure or misspelled track titles
- MusicBrainz rate limiting if the upstream service is overloaded
- Ambiguous results when title is extremely common (e.g. 'Love Song')
- Empty artist credit for recordings with incomplete MusicBrainz data
- Network timeout if MusicBrainz upstream is slow

## How this service works

Search MusicBrainz for recordings (tracks) by title. Returns matches with title, length (ms), artist credit and MBID. Keyless (sends a User-Agent). Useful for resolving song titles to canonical recordings.

## Output

Returns a list of matching MusicBrainz recording objects, each containing the track title, duration in milliseconds, artist credit string, and the unique MusicBrainz Recording ID (MBID). Multiple results may be returned for ambiguous titles.
