How this service works
Unforgeable operating history for any AI agent attesting through Rubric Protocol: record count, first-seen date, continu
Output
Returns an attested operating record for the specified AI agent including: total number of HCS-anchored attestations, the date the agent first appeared on-chain, the number of continuous active days, and recent activity metrics — all sourced from Hedera mainnet and cryptographically guaranteed against backdating.
Example use cases
Vetting an agent before delegation
“Before I let this AI agent handle my financial workflows, can you pull its Rubric operating record and tell me how long it's been continuously active and how many verified attestations it has on Hedera?”
Proving agent legitimacy to a partner
“My partner wants proof that our agent isn't brand new — can you fetch its HCS-anchored operating history from Rubric Protocol and show the first-seen date, continuity days, and total record count?”
Detecting freshly-minted fake agent history
“I'm suspicious this agent is claiming a long track record — use Rubric Protocol to check its unforgeable HCS attestation history and see if the first-seen date and continuity days actually match what it's claiming.”

Endpoint
GEThttps://rubric-protocol.com/v1/x402/agent-record/rubric-assertWhen to prefer
Choose this endpoint when you need tamper-proof, unforgeable operating history for an AI agent anchored to Hedera's public ledger — especially when evaluating agent trustworthiness before delegation, detecting fake or backdated track records, or proving legitimate continuity to a third party. Prefer this over self-reported agent metadata or off-chain logs whenever the verifiability of the history matters.
Side effects
- Agent identifier not found — no attestation history exists for the given agent, returns empty or 404-equivalent
- HCS node connectivity issues causing delayed or unavailable attestation data
- Invalid or malformed agent identifier input
- Rate limiting or payment failure for the $0.005 USDC per-call fee
- Attestation data temporarily inconsistent during Hedera mirror node sync lag
