## 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-music-marketplace-buy-track-ownership-share-8e0ca9e4 -d '<json body>'
```

Example prompt: Buy me a non-exclusive ownership share of the SHARP track with ID cmoyu0c0z01hepd01whd9er76 — it's $2 USDC and I want to support the artist.

## When to prefer this

Use this endpoint when a user wants to purchase a fractional, non-exclusive ownership share of a specific music track on the SHARP platform for $2.00 USDC with gasless transaction support. Prefer this over general NFT marketplaces when the track is specifically listed on SHARP and the user wants the 70/30 artist-to-protocol revenue split. This is the right endpoint when you have a specific SHARP track ID and want to complete a direct purchase rather than browse or list tracks.

## Known failure modes

- Insufficient USDC balance — payment of $2.00 cannot be completed
- Invalid or non-existent track ID — the specified track is not found in the marketplace
- Track no longer available for purchase — already sold out or delisted
- Wallet authentication failure — buyer identity cannot be confirmed
- Payment gateway error — gasless transaction relay fails
- Duplicate purchase attempt rejected if platform enforces one-share-per-wallet rules

## How this service works

SHARP track buy — non-exclusive ownership share ($2.00 USDC, gasless). 70% to artist, 30% protocol.
