## 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`):

## When to prefer this

Use this endpoint when you want to purchase a non-exclusive ownership share of a specific SHARP music track (identified by its track ID) for a flat $2.00 USDC fee with gasless execution. Prefer this over general music streaming or NFT marketplaces when the goal is direct artist support via the SHARP platform's revenue-sharing model.

## Known failure modes

- Insufficient USDC balance — payment fails with insufficient funds error
- Invalid or expired track ID — track may no longer be available for purchase
- Duplicate purchase attempt — same buyer may already own a share
- Payment gateway timeout — gasless relay may be temporarily unavailable
- Network error on Railway deployment — server may be unreachable
