## 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 sharp-track-buy-non-exclusive-ownership-share-e92ccf42 -d '<json body>'
```

Example prompt: Buy me a non-exclusive ownership share of the SHARP track with ID cmpctk6n9001ho101ywg4bd5g for $2 USDC — I want to support the artist and hold a stake in the song.

## When to prefer this

Use this endpoint when an agent or user wants to purchase a non-exclusive ownership stake in a specific SHARP music track using USDC. Prefer this over generic NFT marketplaces when the track ID is known and the goal is a low-cost ($2), gasless music ownership transaction that directly supports the artist via the 70/30 revenue split.

## Known failure modes

- Insufficient USDC balance — payment fails with 402 or insufficient funds error
- Invalid or non-existent track ID — 404 not found response
- Wallet address missing or malformed — 400 bad request
- Network or Railway hosting downtime — 503 service unavailable
- Duplicate purchase attempt on a track with limited supply — conflict or sold-out error
