# Tanod chainpeek Latest Block

> Tanod chainpeek Latest Block is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Returns the latest block's number, timestamp, hash, base fee, and gas used/limit for Ethereum or Base.

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 tanod-chainpeek-latest-block-3301310c -d '<json body>'
```

Example prompt: What are the details of the latest block on Ethereum right now — block number, timestamp, hash, base fee, and gas used?

## When to prefer this

Use this endpoint when you need a quick, read-only snapshot of the latest block metadata (number, timestamp, hash, base fee, gas used/limit) on Ethereum or Base without running your own node. Prefer it over a full node RPC call when you want a simple HTTP API with pay-per-call pricing and no node infrastructure to manage. If you only need gas price data rather than full block metadata, the sibling chainpeek gas endpoint may be more appropriate.

## Known failure modes

- Invalid or unsupported chain value — only 'ethereum' and 'base' are accepted; other values return a validation error
- Network or RPC connectivity issues may return a 5xx error if the upstream node is unreachable
- Payment failure or insufficient USDC balance returns a 402 Payment Required response
- Malformed request body returns a 400 Bad Request
