## When to prefer this

Use this endpoint when a user wants to acquire a non-exclusive ownership share of a specific SHARP music track identified by its track ID, paying $2.00 USDC in a gasless transaction. Prefer this over generic music streaming or download services when the goal is to own a stake in a track and directly support an artist through the SHARP creator economy model.

## Known failure modes

- Insufficient USDC balance — payment of $2.00 cannot be completed
- Invalid or expired track ID — track may no longer be available for purchase
- Duplicate purchase attempt — ownership already recorded for this wallet/track combination
- Payment gateway timeout — gasless transaction relay failure
- Track sold out or delisted from marketplace
