• GET/api/uuid—No price listedUUIDs on demand: version 4 (random) or version 7 (time-ordered, sortable), up to 100 per call. Use it when an agent needs identifiers for records, requests or files, or a sub-cent call to test an x402 client end to end before buying anything larger. Also on x402 Bazaar

• POST/api/sql-cert-verify—No price listedVerify an Ed25519 execution certificate against the exact SQL statement you are about to run - the gate your database layer calls before it obeys an agent.
