# Ethereum Network Info Summary

> Ethereum Network Info Summary is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).

Returns a real-time snapshot of the Ethereum network state including latest block number, gas price, chain ID, and sync status.

## Facts

- Endpoint: GET https://ari001.tailb4ac3a.ts.net/v1/ventures/ethereum_contract_abi_service/network_info_summary?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ethereum-network-info-summary-b6e57472
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_tm85V4iZ5FG8g1YgfF3NW

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-network-info-summary-b6e57472
```

Example prompt: What are the current Ethereum network stats — give me the latest block number, current gas price, and base fee per gas right now.

## When to prefer this

Choose this endpoint when you need a fast, single-call snapshot of Ethereum network state without constructing raw RPC calls. It is ideal for pre-transaction gas estimation, network health checks, or confirming chain ID before contract interactions. Prefer this over raw eth_gasPrice or eth_blockNumber RPC calls when you want multiple network stats in one request at low cost ($0.002 USDC).

## Known failure modes

- Node connectivity issue — the upstream Ethereum node may be unreachable, returning ok: false with an error message
- Sync lag — the node may be behind the canonical chain head, returning stale block data
- Rate limiting or payment failure — the x402 payment may be rejected, blocking the request
- Invalid response format if the Ethereum RPC is returning unexpected data

## How this service works

Returns a summary of the Ethereum network's current state: latest block number, gas price, chain ID, and sync status.

## Output

A JSON object containing the current Ethereum network state: chain_id (integer), block_number (latest block height), gas_price_wei (current gas price in wei), base_fee_per_gas_wei (EIP-1559 base fee), block_gas_used and block_gas_limit (gas metrics), block_timestamp (Unix timestamp of latest block), and block_transactions (transaction count in latest block). Also includes ok (boolean) and service identifier fields.
