## 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-soneium-latest-block-052c2215 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need real-time, low-latency access to the latest Soneium block without running your own RPC node. Prefer this over generic Ethereum endpoints when your workflow is specifically targeting the Soneium network. Ideal for agents that need to monitor chain progress, confirm transaction finality, or sync application state with the Soneium chain head on demand.

## Known failure modes

- Network unavailability on Soneium RPC node returns 5xx error
- Payment not included or insufficient USDC via x402 returns 402 Payment Required
- Malformed request body returns 400 Bad Request
- Node sync lag may return a slightly stale block during network congestion

## How this service works

## Output

Returns the latest block object from the Soneium blockchain, including block number, block hash, parent hash, timestamp, gas used, gas limit, miner address, and list of transactions or transaction hashes included in the block.
