## 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 unprice-base-block-lookup-9fa61222
```

Example prompt: What is the latest block on the Base network — give me the block number, hash, and timestamp?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-request access to the latest Base blockchain block metadata (hash, number, timestamp) without running your own node or paying for a full RPC subscription. Ideal for agents that need occasional block lookups at $0.001 USDC per call rather than maintaining an always-on connection.

## Known failure modes

- Network or RPC node unavailable — may return 5xx or empty response
- Payment not processed — 402 response if USDC payment via x402 fails
- Malformed properties parameter — may return error or unexpected subset of block fields
- Base network congestion causing stale or delayed block data

## How this service works

Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.

## Output

A JSON object containing the latest Base block's hash (hex string), block number (integer), network name ('base'), and Unix timestamp (integer). Example: {"hash":"0x...","number":12345678,"network":"base","timestamp":1714000000}
