# Tanod ChainPeek Chain Info

> Tanod ChainPeek Chain Info is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

Returns current block, gas, and chain state for Ethereum or Base blockchain networks

## 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 tanod-chainpeek-chain-info-58898c8c -d '<json body>'
```

Example prompt: What are the current gas prices and latest block info on Base right now?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call access to current block and gas data for Ethereum or Base without managing RPC infrastructure or API keys. Ideal for AI agents that need occasional chain state snapshots rather than continuous streaming. At $0.001 USDC per call with no signup required, it suits low-frequency monitoring or pre-transaction gas checks.

## Known failure modes

- Invalid chain value (not 'ethereum' or 'base') returns a validation error
- Payment not included or insufficient USDC results in HTTP 402
- Service unavailable if upstream RPC is down
- Stale data up to 30 seconds due to caching

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a JSON object with the chain name, chain ID, current block number, block timestamp, head age in seconds, base fee in gwei, gas price in gwei and wei, gas used, gas limit, and native token symbol. RPC reads are cached up to 30 seconds.
