🟡notary_quote(work_hash, pdr_version)
Request a notarisation quote for a work artifact. Returns the cost ($0.01 USDC or NEAR equivalent), a quote_id valid for 600 seconds, the sink account to send payment to, and the PDR schema version. Step 1 of the notarisation flow: quote -> pay -> notarize -> verify.

}🟡notary_free(work_hash, content, metadata)
Create a free cryptographic proof of existence (PDR) for a digital artifact without payment. Dual mode: pass work_hash (Mode A, client-computed SHA-256 hex) OR content (Mode B, raw text/code ≤60KB — server hashes it, zero retention). Subject to rate limits (5/IP/day, 1000/day global). Returns shield_id, pdr_b64, and verify_url. For on-chain settlement proof, use notary_notarize_paid ($0.01 USDC on Base).

}🟡notary_notarize(work_hash, tx_hash, artifact_uri, metadata, agent_sig, ...)
Submit a work artifact for on-chain notarisation (NEAR_DIRECT payment path). PREREQUISITE: Send the NEAR amount from notary_quote to the sink account, then provide the resulting tx_hash here. The server verifies the on-chain payment and submits the notarisation. Returns job_id — use notary_verify to poll for the signed PDR. Step 3 of the notarisation flow: quote -> pay -> notarize -> verify.

}⚪notary_verify(job_id)
Verify a notarisation by job_id. Returns status (pending/anchored/error). If anchored, returns the full PDR record (base64, 239 bytes) with Ed25519 signature verification. Step 4 of the notarisation flow: quote -> pay -> notarize -> verify. Can be polled repeatedly until status changes from 'pending' to 'anchored'.

}🟡notary_notarize_paid(work_hash, agent_sig, agent_pubkey)
Notarize a work hash on AOTrust (mainnet NEAR + Base USDC receipt). $0.01 USDC via x402-over-MCP: call without payment to receive PaymentRequired; retry with params._meta['x402/payment'] = signed PaymentPayload (EIP-3009, scheme exact, eip155:8453). HTTP clients: POST /notarize with x-payment header.
