## 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 x402-toolbox-block-transactions-lookup-71f662c8
```

Example prompt: Can you pull all the transactions that were included in a specific block on Base? I want to see what went through in that block.

## When to prefer this

Choose this endpoint when you need deterministic, pay-per-call access to block-level transaction data without signing up for an API key or managing credentials — particularly useful for AI agents operating autonomously with USDC on Base via the x402 payment protocol.

## Known failure modes

- Invalid or unknown block identifier returns an error
- Unsupported chain schema causes a bad request
- Payment failure via x402 results in 402 response and no data returned
- Network congestion may cause delayed responses
- Missing schema parameter may result in a validation error

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with ok and paid status flags along with the list of transactions included in the specified blockchain block, including transaction hashes, addresses, values, and other on-chain metadata.
