## 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-829921ca -d '<json body>'
```

Example prompt: Buy me a non-exclusive ownership share of the SHARP track with ID cmot8ecun0144pa01gw3xg88u — it's $2 USDC and goes 70% to the artist.

## When to prefer this

Use this endpoint when you want to purchase a non-exclusive ownership stake in a specific SHARP music track identified by its track ID, paying exactly $2.00 USDC gaslessly. Prefer this over general NFT marketplaces when the track is listed on the SHARP platform and you want the artist-friendly 70/30 revenue split. This is not for streaming, licensing, or exclusive rights — only non-exclusive fractional ownership shares.

## Known failure modes

- Insufficient USDC balance — payment of $2.00 cannot be completed
- Invalid or expired track ID — track may no longer be available for purchase
- Wallet not connected or missing payment credentials
- Network/Railway infrastructure downtime causing request failure
- Duplicate purchase attempt if idempotency is not enforced by caller
- Gas or x402 payment protocol misconfiguration
