How this service works
Independent audit of a Rubric attestation: signature validity, HCS sequence, and direct Hedera mirror-node confirmation.
Output
A signed audit verdict containing: signature validity status, HCS sequence check result, Hedera mirror-node confirmation, and a new attestation ID for the verdict itself — which can be cited independently as verifiable evidence of the audit.
Example use cases
AI decision audit trail for regulators
“We need to prove to our regulator that the AI trading decision from last Tuesday was genuine — can you run an independent Rubric audit on attestation ID attest-0x7f2a to verify the signature, confirm the Hedera HCS sequence, and give us a signed verdict we can submit as evidence?”
Compliance verification before contract settlement
“Before we settle this smart contract, audit the Rubric attestation attached to the counterparty's AI agent decision — verify its signature validity and mirror-node confirmation, and return a signed audit verdict so we have an immutable record.”
Post-quantum signature integrity check
“Can you audit this Rubric attestation to check whether the post-quantum signature is still intact and the HCS anchoring matches what Hedera's mirror node has on record, then give me a signed verdict with its own attestation ID?”
Technical details
Endpoint
POSThttps://rubric-protocol.com/v1/x402/verify-auditWhen to prefer
Choose this endpoint when you need an independent, citable audit of a Rubric attestation — not just internal validation. It is the right choice when regulatory, legal, or compliance contexts require a third-party-signed verdict with its own attestation ID, or when you need cryptographic assurance that a Hedera HCS-anchored attestation has not been tampered with.
Side effects
- Invalid or malformed attestation input — returns error indicating unrecognizable attestation format
- Signature verification failure — verdict returned with failed signature validity status
- HCS sequence mismatch — verdict indicates sequence inconsistency on Hedera
- Mirror-node unreachable or timeout — returns error if Hedera mirror node cannot be queried
- Payment failure — request blocked if USDC payment of $0.002 is not settled via x402
