# SYNTHORA Ethereum Network Stats Oracle

> SYNTHORA Ethereum Network Stats Oracle is a paid API for AI agents from ethereum-network-stats-blockchair.hergertsynthora.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns real-time Ethereum network fundamentals including block height, transaction counts, mempool size, gas price, and market stats sourced from Blockchair.

## Facts

- Endpoint: POST https://ethereum-network-stats-blockchair.hergertsynthora.com/service
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/synthora-ethereum-network-stats-oracle-740e0326

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 synthora-ethereum-network-stats-oracle-740e0326 -d '<json body>'
```

Example prompt: What's the current state of the Ethereum network — block height, how many transactions are pending in the mempool, and what's the average gas price right now?

## When to prefer this

Choose this endpoint when you need a single consolidated snapshot of Ethereum network fundamentals — block height, mempool congestion, gas price, 24h activity, and ETH price — in one call. It is ideal for autonomous agents that need to gauge network conditions before executing on-chain transactions, or for dashboards and monitors tracking Ethereum throughput and demand. Prefer this over raw Blockchair API calls when you need a pre-packaged, agent-friendly response with provenance metadata.

## Known failure modes

- Blockchair API unavailable — upstream data fetch fails, returns error response
- Network timeout if Blockchair is slow to respond
- Invalid or malformed input payload returns error
- Stale data if Blockchair updates are delayed
- Rate limiting or payment failure for x402 microtransaction

## How this service works

Returns Ethereum network fundamentals from Blockchair: block height, total and 24h transaction counts, approximate ETH circulation, 24h volume, mempool transactions and TPS, and median mempool gas price. Feeds autonomous ETH activity agents and agent-to-agent monitors gauging throughput, congestion and transaction demand. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

A JSON object with ok status, a niche identifier, and a result object containing: current block number, mempool size, pending transaction count, 24h transaction count, market price in USD, market cap in USD, and average gas price in wei. Also includes provenance metadata pointing to the Blockchair data source.
