How this service works
Retrieve an attestation by id with GET /attest/{id}. The gateway prefix-matches this registered path.
Output
Returns a JSON object with the attestation ID, a boolean ok status, a JWS (JSON Web Signature) string, and a payload_hash string representing the cryptographic proof of the attested content.
Example use cases
Verify document signing attestation
“I need to confirm that the document we signed last week is still valid — can you pull up the attestation record for att_3f92a1cd7e4b2d8f and show me the JWS signature and payload hash so I can verify it?”
Audit cryptographic proof record
“We're running a compliance audit and need to check the cryptographic proof for a transaction. Can you retrieve the attestation with ID att_7a45e2bc91d0f3c6 and give me the full JWS token and payload hash for our records?”
Look up identity attestation proof
“A user is claiming their identity was verified — can you look up attestation ID att_1d84c7fa30e5b92a and pull the JWS signature and payload hash so I can confirm the signed proof is legitimate?”
Technical details
Endpoint
GEThttps://gateway.apiosk.com/attestations/attest/att_0bcab6bede9f417ea9506afbf8814848When to prefer
Use this endpoint when you need to retrieve a specific, pre-existing cryptographic attestation by its unique ID and need the JWS signature and payload hash for verification or audit purposes. Prefer this over general identity APIs when the attestation ID is already known and you need the signed proof record.
Side effects
- Attestation ID not found — returns error or empty result
- Invalid attestation ID format — malformed request
- Payment not processed — 402 response if x402 payment header is missing or invalid
- Service unavailable — gateway timeout or upstream error
