## 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 aeris-music-paper-lanterns-track-lookup-8b2e89cc
```

Example prompt: Can you grab the 'paper-lanterns' CC0 royalty-free track from AERIS MUSIC — I need the title, mood tags, and the MP3 download link so I can use it in my project?

## When to prefer this

Choose this endpoint when you need a specific pre-made CC0 royalty-free music track (paper-lanterns) with an immediate MP3 download URL and you are operating in a USDC/Base micropayment context via the x402 protocol. Prefer this over general music APIs when you need zero licensing friction (CC0-1.0) and can pay per call in crypto rather than managing a subscription.

## Known failure modes

- Payment not settled — x402 payment header missing or rejected, returns 402 Payment Required
- Track not found — the slug 'paper-lanterns' does not exist on this worker, returns 404
- Worker unavailable — Cloudflare Workers outage or cold-start timeout
- USDC balance insufficient on Base mainnet — payment fails before response is returned
- MP3 download URL may be a GitHub Pages static link that could become unavailable
