How this service works
Attested Hedera network facts: HBAR exchange rate, gas fees, supply, node roster, throughput, topic state. Each response
Output
A structured JSON snapshot of Hedera network staking facts — including node roster, staking rates, HBAR exchange rate, gas fees, token supply, throughput, and topic state — accompanied by an ML-DSA-65 (post-quantum) attestation ID that cryptographically anchors the snapshot and proves its contents have not been tampered with.
Example use cases
Audit trail for staking decisions
“Pull the current attested Hedera staking snapshot from Rubric Protocol — I need the node roster and attestation ID on record so our compliance team can verify what staking data the agent used when it rebalanced the portfolio.”
Verify Hedera node roster integrity
“Get me the post-quantum-signed Hedera node roster right now — I want to confirm no unauthorized nodes have appeared and keep the ML-DSA-65 attestation ID as proof of what we observed.”
Smart contract pre-execution data proof
“Before we execute this Hedera smart contract, fetch the attested staking and network facts so we have a tamper-evident record of current gas fees and node roster that we relied on going into this transaction.”
Technical details
Endpoint
GEThttps://rubric-protocol.com/v1/x402/hedera-facts/stakingWhen to prefer
Choose this endpoint when your agent needs cryptographically provable, tamper-evident Hedera staking data — especially in compliance, audit, or decision-tracing contexts where you must prove exactly what network facts were observed at the time of action. It is preferable over raw RPC or unattested data feeds when post-quantum signature attestation (ML-DSA-65) is required as evidence.
Side effects
- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Hedera network temporarily unavailable — snapshot may be stale or endpoint returns 503
- Invalid or malformed GET request — returns 400 Bad Request
- Rate limiting exceeded — returns 429 Too Many Requests
- Attestation service temporarily unavailable — may return partial data without attestation ID
