## 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 delx-base-latest-block-5c383dc6 -d '<json body>'
```

Example prompt: What's the latest block on Base mainnet right now — give me the block number, hash, timestamp, and gas info?

## When to prefer this

Choose this endpoint when you need a single, real-time Base mainnet block header without managing your own RPC node or API key — ideal for agents that need lightweight chain-tip checks, gas estimates from recent blocks, or timestamp anchoring in a pay-per-call model at $0.001 USDC.

## Known failure modes

- RPC node unavailable or rate-limited — returns 5xx error
- Payment not processed correctly via x402 protocol — returns 402 Payment Required
- Network congestion causes delayed or stale block response
- Malformed response if Base network experiences reorg at query time
