Example prompt: Buy me a non-exclusive ownership share of the SHARP track with ID cmp4jmv1l00yirr010iigcfee for $2 USDC — I want to support the artist and hold a stake in the track.

## When to prefer this

Use this endpoint when you want to purchase a non-exclusive ownership share of a specific, identified SHARP music track for exactly $2.00 USDC with gasless transaction support. Prefer this over generic NFT marketplaces when the track ID is known and the goal is direct artist support with a transparent revenue split (70/30).

## 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
- Wallet authentication failure — buyer wallet not properly authorized
- Network error on Railway deployment — service temporarily unavailable
- Duplicate purchase attempt on non-idempotent endpoint — may result in multiple charges
