## 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-a7b71be0 -d '<json body>'
```

Example prompt: Buy me a non-exclusive ownership share of the SHARP track with ID cmo2it9qn00fdlp01jhdyz1zh for $2 USDC — I want to support the artist and hold a piece of that track.

## When to prefer this

Use this endpoint when you want to purchase a non-exclusive fractional ownership share of a specific SHARP music track for a flat $2.00 USDC fee with gasless execution. Prefer this over general NFT marketplaces when the track is specifically listed on the SHARP platform and you want the artist to directly receive 70% of your payment.

## Known failure modes

- Insufficient USDC balance — payment of $2.00 USDC fails
- Track ID not found or no longer available on marketplace
- Duplicate purchase attempt for the same track by same buyer
- Payment authorization or x402 header missing or malformed
- Network or railway deployment downtime causing 503 errors
