ModelPin · x402
An on-chain registry for 3D assets where every metadata fetch, preview render, or provenance check is an atomic 0.01 USDC transaction. Instead of a static database, it is a living ledger where studios and collectors pay per query to verify geometry integrity and licensing history. Each 'pin' is a cryptographically signed state, unlocked by an x402 stream, ensuring that high-fidelity documentation is monetized at the point of access.
The primitive.
Access to the 3D model documentation engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so filmmakers — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveBy moving from a storage-heavy model (IPFS) to a logic-heavy payment model (x402), you turn documentation from an overhead cost into a recurring revenue stream. It prevents scraping and ensures that only authorized entities verify model technicals via micropayment.
