Creates and verifies cryptographic proof-of-existence records, including paid on-chain notarization using NEAR or USDC.

Funktionen

Tools

5 Tools
notary_free
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).
Eingabeschema 
{'type': 'object', 'properties': {'content': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}, 'metadata': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}, 'work_hash': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None}}, 'additionalProperties': False}
Ausgabeschema 
{'type': 'object', 'additionalProperties': True}
notary_notarize
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.
Eingabeschema 
{'type': 'object', 'required': ['work_hash', 'tx_hash'], 'properties': {'tx_hash': {'type': 'string'}, 'metadata': {'type': 'string', 'default': '{}'}, 'agent_sig': {'type': 'string', 'default': ''}, 'work_hash': {'type': 'string'}, 'agent_pubkey': {'type': 'string', 'default': ''}, 'artifact_uri': {'type': 'string', 'default': ''}}, 'additionalProperties': False}
Ausgabeschema 
{'type': 'object', 'additionalProperties': True}
notary_notarize_paid
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.
Eingabeschema 
{'type': 'object', 'required': ['work_hash'], 'properties': {'agent_sig': {'type': 'string', 'default': ''}, 'work_hash': {'type': 'string'}, 'agent_pubkey': {'type': 'string', 'default': ''}}, 'additionalProperties': False}
Ausgabeschema 
{'type': 'object', 'additionalProperties': True}
notary_quote
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.
Eingabeschema 
{'type': 'object', 'properties': {'work_hash': {'type': 'string', 'default': ''}, 'pdr_version': {'type': 'string', 'default': '2.3'}}, 'additionalProperties': False}
Ausgabeschema 
{'type': 'object', 'additionalProperties': True}
notary_verify
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'.
Eingabeschema 
{'type': 'object', 'required': ['job_id'], 'properties': {'job_id': {'type': 'string'}}, 'additionalProperties': False}
Ausgabeschema 
{'type': 'object', 'additionalProperties': True}
