How this service works
Attested Hedera network facts: HBAR exchange rate, gas fees, supply, node roster, throughput, topic state. Each response
Output
A JSON object containing the rubric-activity snapshot of Hedera network facts: HBAR/USD exchange rate, current gas fee schedule, total HBAR supply, active node roster, network throughput metrics, and HCS topic state — each snapshot accompanied by an ML-DSA-65 (post-quantum) attestation ID that cryptographically binds the data to the specific moment it was served, enabling agents to prove what they knew at decision time.
Example use cases
Audit trail for automated HBAR transaction
“Before I execute this HBAR transfer, grab me the current Hedera gas fees and exchange rate from Rubric Protocol's rubric-activity endpoint — I need the attestation ID so I can log exactly what the network state was when the trade ran.”
Compliance snapshot for AI agent decision log
“My AI agent just made a governance decision on Hedera — pull the attested Hedera network facts right now, including the node roster and topic state, so I can anchor the attestation ID in my compliance record.”
Real-time Hedera network health dashboard
“Can you fetch the latest Hedera throughput, supply, and gas fee data from Rubric Protocol with post-quantum attestation, so my dashboard can display current network health with a tamper-evident proof?”
Technical details
Endpoint
GEThttps://rubric-protocol.com/v1/x402/hedera-facts/rubric-activityWhen to prefer
Choose this endpoint when your agent or application needs cryptographically provable, tamper-evident Hedera network state — particularly for compliance, audit logging, or any use case where you must later prove what the network conditions were at a given moment. Prefer it over plain Hedera API calls when post-quantum attestation (ML-DSA-65) is required, or when regulatory or contractual obligations demand a signed reference datum. Use the bundle endpoint instead if you need all six facts in a single call.
Side effects
- Payment not provided or invalid x402 payment header → 402 Payment Required
- Hedera network temporarily unavailable → upstream data fetch failure, 503 or error body
- Attestation signing service down → snapshot returned without attestation ID or error
- Malformed request → 400 Bad Request
- Rate limiting or quota exceeded → 429 Too Many Requests
