## 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 vextorium-evm-latest-block-info-d22d58b1 -d '<json body>'
```

Example prompt: What does the latest block on Ethereum look like right now — block number, hash, age, how many transactions, gas used, and base fee?

## When to prefer this

Choose this endpoint when you need real-time latest block metadata across Base, Ethereum, Arbitrum, Optimism, or Polygon in a single call — especially when you need a combination of block number, hash, age, transaction count, gas usage, and base fee together rather than just gas price alone. Prefer this over the sibling gas price endpoint when you need block-level context rather than purely fee estimation.

## Known failure modes

- Unsupported network name returns an error or null fields
- Network RPC node unavailable causes timeout or null response
- Invalid body type (not json/form-data/text) causes a 400-level error
- Missing required 'input' wrapper in request body causes schema validation failure

## How this service works

Latest block on an EVM chain: number, hash, time, age in seconds, transaction count, gas used % and base fee.

## Output

Returns a JSON object containing the network name, latest block number, block hash, UTC datetime string, age of the block in seconds, number of transactions included, gas used as a percentage of the gas limit, and the base fee in gwei. All fields may be null if data is unavailable.
