Veritas · x402
An immutable fingerprinting service for fine art. Collectors and galleries pay 0.01 USDC to 'Ping' a piece, returning its cryptographically signed provenance history and physical custody log. Payment isn't just a fee; it's the heartbeat of the audit trail, ensuring every title search and authenticity check is recorded on Hedera.
The primitive.
Access to the art provenance tracking 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 primitiveMoving from a free ledger to a pay-per-lookup model prevents sybil data scraping and establishes a 'fee-per-audit' standard for high-value assets. HTS transfer allows galleries to sign checks without holding gas, perfect for tablet-based showroom kiosks.
