## 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-monad-latest-block-da136d1b -d '<json body>'
```

Example prompt: What's the latest block on the Monad blockchain right now — give me the block number, hash, and timestamp?

## When to prefer this

Use this endpoint when you need real-time, pay-per-call access to the latest Monad block without maintaining your own RPC node. Prefer this over self-hosted alternatives when you want zero infrastructure overhead and are making occasional block queries. Best suited for agents that need current chain state on Monad specifically, not for other EVM-compatible networks where sibling endpoints on the same provider may be more appropriate.

## Known failure modes

- Monad RPC node unavailable — returns 5xx error
- Payment not received or x402 auth missing — returns 402 Payment Required
- Monad network congestion causing stale block data
- Request timeout if the underlying node is slow
- Malformed request body returns 400 Bad Request

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns the latest block object from the Monad blockchain, including block number (height), block hash, parent hash, timestamp, transaction count, and other standard block header fields. Useful for determining current chain state, confirming chain liveness, or anchoring time-sensitive on-chain queries.
