# Ethereum Mainnet Network Info Summary

> Ethereum Mainnet Network Info Summary is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.002/call, status down (last checked 2026-10-30).

Returns a real-time summary of the Ethereum mainnet network state as read directly from the node at call time.

## Facts

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 ethereum-mainnet-network-info-summary-41b4e182
```

Example prompt: Can you pull the current Ethereum mainnet network summary straight from the node and tell me what it says?

## When to prefer this

Choose this endpoint when you need a broad, real-time summary of Ethereum mainnet network state in a single call, without needing to specify any parameters. Prefer it over narrower endpoints (like eth_chainId or eth_blockNumber) when you want a combined network overview rather than a single specific value.

## Known failure modes

- Node unreachable or offline — returns connection error or timeout
- Upstream node returns stale or incomplete data
- x402 payment failure — request rejected if payment header is invalid or insufficient
- Rate limiting if too many requests are made in quick succession

## How this service works

ARYSPHERE sells AI-written verdicts on Base token contracts (a grade, a one-liner, a roast and the contract's facts) and Base/Ethereum chain reads, paid per call in USDC on Base over x402 v2. No account and no API key.

## Output

A JSON object containing an Ethereum mainnet network summary as read from the node at the moment of the call, including network-level state data such as chain ID, node-reported network information, and related fields.
