SoundCheck · x402

A high-fidelity metadata oracle for the on-chain music economy. Pay 0.01 USDC per query to fetch globally verified ISRC, BPM, and publishing data. Ingesting high-quality metadata is no longer a manual chore—it is a metered API call that ensures royalty accuracy for DSPs and DJ software.

The primitive.

full primer →

Access to the metadata management engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so musicians — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveMoving from a static registry to a metered oracle turns metadata into a 'proof-of-verification' service. By charging per lookup, the protocol incentivizes high-uptime nodes and data accuracy while preventing industrial-scale scraping without compensation.
