Genexxis Notary Time
x402
Genexxis Notary Time is a paid API for AI agents from notary.genexxis.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).
Returns the current UTC time (ISO 8601 and Unix milliseconds) cryptographically signed by the Genexxis notary key, along with the message and signature for independent verification.

How this service works
Current UTC time (ISO and unix ms) signed by the genexxis notary key, with the signed message and signature for independent verification.
Output
A JSON object containing the current UTC time as an ISO 8601 string and Unix milliseconds, the signer's Ethereum address, a labeled notary message string (e.g. 'genexxis-notary:v1|time|<timestamp>'), a 65-byte cryptographic signature over that message, and the time source description ('server clock (NTP-synced host)'). The signature can be independently verified against the signer address.
Example use cases
Audit trail timestamp for contract signing
“I'm finalizing a contract and need a cryptographically signed, independently verifiable timestamp of exactly when it was executed — can you fetch a notarized UTC time with the signature from the Genexxis notary?”
Proof-of-time for blockchain event logging
“I need to record a verifiable timestamp for a blockchain event log entry — get me the current UTC time along with the Genexxis notary signature so I can embed it as cryptographic proof.”
Dispute resolution time verification
“Can you grab the current time from the Genexxis notary with its signed message and signature? I need it to prove the exact moment I submitted something in case there's a dispute later.”
Technical details
Endpoint
GEThttps://notary.genexxis.com/time?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically attested, independently verifiable proof of the current time — for example, for audit trails, contract timestamping, dispute resolution, or blockchain event logging. It is preferable over unauthenticated time APIs when the integrity and non-repudiation of the timestamp matters, and over generic NTP sources when you need a human-readable signed artifact you can store and verify later.
Side effects
- Service unavailable (502/503) if the notary server is down
- Payment failure (402) if the x402 USDC payment is not provided or insufficient
- Stale or incorrect timestamp if the NTP sync is disrupted on the host
- Signature verification failure on the client side if the signer address changes unexpectedly
