## 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 sftunes-public-tape-catalog-21b159f7
```

Example prompt: Can you pull up the SFtunes tape catalog and show me the full list of public mixtapes, or if I have a specific tape ID like 'a3f2c1d4-...', fetch its liner notes and music service links?

## When to prefer this

Use this endpoint when you need to browse or retrieve mixtape data from the SFtunes public catalog — either to list all available tapes or to get detailed liner notes and streaming links for a specific tape by UUID. Prefer this over generic music APIs when the user specifically references SFtunes mixtapes.

## Known failure modes

- Invalid or non-existent tape UUID returns an error or empty result
- Network or payment failure (x402 micropayment not processed) prevents access
- Malformed UUID format may cause a bad request error
- Catalog may be empty or unavailable if service is down

## How this service works

SFtunes catalog for agents: index of public mixtapes and public Top 10 lists, or one item with liner notes and music-service links via ?id=<uuid> (tape) or ?id=top10-<handle> (a person's Top 10 + Side B).

## Output

Returns either a full index of public mixtapes (when no ID is provided) or a single tape record including liner notes and links to music streaming services (when a valid tape UUID is supplied via ?id=<uuid>).
