## 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 phantom-api-world-chain-latest-block-b0f17fea -d '<json body>'
```

Example prompt: What's the latest block on World Chain right now — give me the block number, hash, and timestamp.

## When to prefer this

Choose this endpoint when you specifically need real-time latest block data from the World Chain network and want pay-per-call pricing with no subscription overhead. Prefer this over general-purpose RPC providers when you want a simple HTTP POST interface with x402 micropayment support and no API key management. Best suited for agents that need occasional block lookups rather than high-volume streaming.

## Known failure modes

- Network congestion or RPC node downtime may cause timeouts or empty responses
- World Chain node sync lag may return a block that is slightly behind the true head
- Payment failure via x402 protocol results in 402 response and no data returned
- Malformed request body may return a 400 or 422 validation error
- Service unavailability on Vercel hosting may produce 500 or 503 errors

## Output
