## When to prefer this

Use this endpoint when a user specifically wants to purchase a non-exclusive ownership share in an identified SHARP marketplace track (by track ID) using $2 USDC via a gasless transaction. Prefer this over generic music streaming or NFT endpoints when the target is the SHARP platform's creator-economy model with explicit artist revenue sharing.

## Known failure modes

- Invalid or non-existent track ID — returns 404 not found
- Duplicate purchase attempt — may return conflict if ownership already held
- Network/Railway service unavailability — returns 5xx error
- Payment processing failure — gasless relay issue
