## 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 2s-music-artist-search-8d33e843
```

Example prompt: Look up the MusicBrainz artist record for 'Radiohead' and give me their MBID, country, and the year they were formed — return up to 5 results.

## When to prefer this

Use this endpoint when you need ground-truth, structured artist metadata from MusicBrainz — especially when you need the canonical MBID for downstream music API calls, need to disambiguate similarly-named artists, or need factual data like country of origin, artist type, or formation/disbandment year. Prefer over general web search when structured, licensed music metadata is required.

## Known failure modes

- No results found if name is too obscure or misspelled — returns empty items array with total=0
- Invalid limit parameter (outside 1-25) returns a validation error
- Missing required name or query parameter returns an error
- Payment failure via x402 if insufficient USDC balance

## How this service works

Resolve a music artist from MusicBrainz (CC0). Pass a name (or free-text/Lucene query). Returns ranked artists with MusicBrainz ID (MBID), name, sort name, type (Person/Group), country, gender, life span (begin/end/ended), and disambiguation. Keyless, public-domain core data. Use to canonicalize an artist to its MBID.

## Output

Returns a paginated list of matching artist records from MusicBrainz, each with MBID, canonical name, sort name, artist type (Group/Person/etc.), country of origin, active status (ended), lifespan begin/end dates, disambiguation note, and a relevance score. Also includes source attribution (MusicBrainz URL and CC0 license info).
