How this service works
Attested Hedera network facts: HBAR exchange rate, gas fees, supply, node roster, throughput, topic state. Each response
Output
A JSON response containing the current HBAR treasury balance figure as a snapshot from the Hedera network, accompanied by an ML-DSA-65 (post-quantum) attestation ID that cryptographically binds the data to the moment it was served, enabling downstream systems to prove the balance value was not tampered with.
Example use cases
Audit trail for automated HBAR decisions
“Pull the attested Hedera treasury balance right now and save the attestation ID alongside my trade record so I can prove what the supply looked like when my agent acted.”
Compliance snapshot before token issuance
“Before we proceed with the token issuance workflow, grab the current HBAR treasury balance from Rubric Protocol with its cryptographic attestation so our compliance team has a tamper-evident record.”
Real-time treasury monitoring dashboard
“Fetch the latest attested Hedera treasury balance so I can update my monitoring dashboard and flag any significant change from yesterday's snapshot.”
Technical details
Endpoint
GEThttps://rubric-protocol.com/v1/x402/hedera-facts/treasury-balanceWhen to prefer
Choose this endpoint when your agent needs a cryptographically provable, post-quantum-attested record of the Hedera treasury balance — particularly for compliance, audit, or accountability workflows where you must prove what data your agent relied on. Prefer it over raw Hedera API calls when tamper-evidence and attestation provenance are required, and over the bundle endpoint when you only need treasury balance without the overhead of fetching all six Hedera facts.
Side effects
- Payment not settled via x402 protocol returns 402 Payment Required
- Hedera network unavailable or lagging causes stale snapshot or timeout
- Invalid or missing x402 payment header returns authentication/payment error
- Rate limiting if too many calls in rapid succession
- Snapshot attestation ID may reference a recently sealed block, introducing slight lag from real-time
