How this service works
Attested Hedera network facts: HBAR exchange rate, gas fees, supply, node roster, throughput, topic state. Each response
Output
A JSON snapshot of the Hedera mainnet node roster — including node IDs, endpoints, and status — accompanied by an ML-DSA-65 post-quantum attestation ID that serves as a tamper-evident, Hedera-anchored reference proving exactly what node data was served at the moment of the call.
Example use cases
Auditable agent decision logging
“I need a tamper-evident snapshot of the Hedera node roster right now — include the attestation ID so our compliance team can verify exactly what network state my agent saw before it submitted that transaction.”
Node roster validation for smart contract deployment
“Before I deploy this contract to Hedera, pull the attested node roster so I can confirm which nodes are active and have a signed receipt proving the network state I used to make that call.”
Regulatory audit trail for AI agent actions
“Get me the post-quantum-signed Hedera node roster with its attestation ID — I need to attach this as evidence to our regulatory filing showing what infrastructure state the agent was operating against at timestamp of execution.”
Technical details
Endpoint
GEThttps://rubric-protocol.com/v1/x402/hedera-facts/nodesWhen to prefer
Choose this endpoint when your agent needs not just the Hedera node roster but also a cryptographically signed, post-quantum attestation proving what it was told — essential for compliance, audit trails, regulatory filings, or any workflow where you must demonstrate the exact network state your agent acted upon. Prefer this over unauthenticated Hedera mirror node queries when tamper-evidence and non-repudiation are required.
Side effects
- Hedera mirror node unavailable — upstream data cannot be fetched, returns 503 or error payload
- Payment not processed — x402 payment verification fails, returns 402
- Attestation signing failure — ML-DSA-65 signing service unavailable, request may fail or return unsigned data
- Stale snapshot — data may be seconds to minutes old depending on Hedera mirror node latency
- Malformed request — non-GET method returns 405
