 "description": "Signed time and hash receipts for agents. GET /time returns the current UTC time signed by the genexxis notary key; POST /stamp takes a SHA-256 hash (+ optional label) and returns a signed receipt (id, timestamp, message, EIP-191 signature) stored for lookup. This is a server-signed timestamp: proof that the hash existed at that time according to this service (NTP-synced clock), not an on-chain anchor. Verification is free (POST /verify, GET /receipt) and also works offline with any Ethereum personal_sign verifier against signer 0x02A5A59fdC30Ec50c091F7EE1486D08B49F56940.",
