## 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 losbeto-chain-block-data-f867735f
```

Example prompt: What is the current block number on the Base network right now? Pay for it with USDC via x402 — no API key needed.

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call blockchain block data (block number or timestamp) for chains like Base, Solana, Algorand, or Polygon without setting up API keys or accounts. Ideal for AI agents that need occasional on-chain lookups and want to pay in USDC micropayments via x402.

## Known failure modes

- Missing or invalid chain identifier returns an error or empty result
- Payment failure via x402 results in 402 Payment Required response
- Unsupported chain returns a not-found or unsupported error
- Network timeout if the target chain RPC is slow or unavailable
