## 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-64f69f69 -d '<json body>'
```

Example prompt: Buy me a non-exclusive ownership share of the SHARP track cmov5k3hq00fxpd01uhwsfx2c for $2 USDC — gasless payment, 70% goes to the artist.

## When to prefer this

Use this endpoint when an agent or user wants to acquire a non-exclusive ownership stake in a specific SHARP music track for a flat $2.00 USDC fee with gasless execution. Prefer this over general NFT purchase endpoints when the target is a SHARP marketplace track specifically, and when the user wants the artist-direct 70/30 revenue split model.

## Known failure modes

- Insufficient USDC balance — payment of $2.00 cannot be completed
- Invalid or expired track ID — track cmov5k3hq00fxpd01uhwsfx2c may no longer be available
- Payment authorization failure — wallet not connected or x402 payment header missing
- Track already sold out of available shares
- Network or Railway server downtime causing 5xx errors
- Duplicate purchase attempt flagged by protocol
