# Rubric Protocol Hedera Throughput Facts

> Rubric Protocol Hedera Throughput Facts is a paid API for AI agents from rubric-protocol.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns attested Hedera network throughput metrics (transactions per second, etc.) with a post-quantum ML-DSA-65 attestation ID proving the data snapshot's integrity.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rubric-protocol-hedera-throughput-facts-677b45a9
```

Example prompt: Fetch the current Hedera network throughput from Rubric Protocol and give me the attested TPS figure along with the ML-DSA-65 attestation ID so I can prove what the network was doing when my agent made its decision.

## When to prefer this

Choose this endpoint when an AI agent or automated system needs cryptographically provable Hedera throughput data — not just the raw metric, but tamper-evident proof of what was known at decision time. It is the right choice for compliance workflows, audit trails, and any scenario where an agent must demonstrate the network conditions under which it acted, using post-quantum-secure attestation anchored to Hedera HCS.

## Known failure modes

- Payment not settled (x402 payment required before data is served)
- Hedera mirror node temporarily unavailable causing stale or missing snapshot
- Invalid or expired attestation if snapshot window has lapsed
- Network timeout if Hedera mainnet connectivity is degraded

## 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 current Hedera network throughput (e.g. transactions per second), accompanied by an ML-DSA-65 post-quantum attestation ID that uniquely identifies the served data snapshot, enabling downstream verification that the data has not been tampered with.
