ORIGIN · x402

Verify print authenticity and provenance history in real-time. Each scan or 'Proof of Ownership' lookup costs $0.01 USDC, preventing mass scraping of high-res certificates while ensuring a permanent ledger of chain-of-custody. Collectors pay to claim; flippers pay to verify.

The primitive.

full primer →

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

Why this primitiveProvenance is high-value but low-bandwidth data. By metering the verification process, you turn a passive certificate into an active, revenue-generating security primitive that discourages sybil-verification scripts.
