The primitive.

full primer →

Access to the exhibit state recording 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 primitiveBy turning each 'state record' into a paid transaction, the act of archiving gains economic weight and permanence. It prevents database bloat and ensures that only high-value snapshots are written to the chain, creating a premium historical ledger for the art market.
