Rubric Protocol Attested Work Record
x402
Rubric Protocol Attested Work Record is a paid API for AI agents from rubric-protocol.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Creates a post-quantum-signed, Hedera-anchored attestation of who or what performed a specific action, its outcome, and any deviation from the original plan — forming a tamper-evident operational log entry.

How this service works
Attested work record for mixed human/robot/agent crews: seal who (or what) did which action, the outcome, and any deviat
Output
Returns a signed attestation receipt containing the ML-DSA-65 cryptographic signature over the work record, a Hedera HCS topic message ID anchoring the record to mainnet, a timestamp, a unique record identifier, and a verifiable payload capturing the actor(s), action, outcome, and any plan deviation — independently verifiable by any third party without trusting the issuing service.
Example use cases
AI agent incident investigation log
“My fulfillment agent just completed a warehouse pick-and-pack job but deviated from the planned route — seal a tamper-proof work record showing agent-42 performed a POST action, the outcome was partial completion, and the deviation was an unplanned aisle reroute, so we have it for the incident review.”
Insurance dispute evidence for drone delivery
“Our delivery drone completed the drop-off but the customer is disputing it — create an attested work record anchored to Hedera showing drone-unit-9 executed the delivery action via POST, the outcome was confirmed drop-off, and there was no deviation from the flight plan, so we can present it as evidence.”
Compliance audit trail for mixed human-AI crew
“We just finished a financial reconciliation task split between a human analyst and our AI assistant — seal a Rubric work record documenting both actors, the reconciliation POST action, the matched-balance outcome, and zero deviation from the approved procedure, for our quarterly compliance audit.”
Technical details
Endpoint
POSThttps://rubric-protocol.com/v1/x402/attested-work-recordWhen to prefer
Choose this endpoint when you need a cryptographically non-repudiable, independently verifiable record of who or what performed an action — especially in mixed human/AI/robot crews where accountability is legally or operationally critical. It is the right choice for incident investigations, insurance disputes, compliance audits, or any workflow where you need a post-quantum-resistant signature (ML-DSA-65) and a blockchain anchor (Hedera HCS) rather than a simple database log entry. Prefer it over generic logging services when third-party verifiability without trusting the log custodian is a hard requirement.
Side effects
- Missing required actor or action fields returns a 400 validation error
- Malformed input schema (wrong HTTP method or type) returns a 422 unprocessable entity
- Payment not settled via x402 protocol returns a 402 Payment Required
- Hedera HCS congestion or unavailability may delay anchoring and return a 503
- Signature generation failure returns a 500 internal server error
- Duplicate submission of an identical record is not deduplicated — each call produces a new unique attestation
