Sonic Tap · Pay to Verify

A library of high-fidelity instrument samples where every 'note on' event or file download executes an QUIP micropayment. Creators stream revenue per individual beat used in a DAW, rather than selling bulk packs that get pirated. Built for the era of AI-generated music and real-time collaborative production. Anyone can pay 0.01 USDC over x402 to verify someone else's QUIP chain and walk away with a receipt.
