# Vextorium Latest EVM Block

> Vextorium Latest EVM Block is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-28).

Returns the latest block details for a specified EVM chain, including block number, hash, timestamp, age in seconds, transaction count, gas utilization percentage, and base fee in gwei.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-latest-evm-block-9be74e05 -d '<json body>'
```

Example prompt: What does the latest block on Base look like right now — give me the block number, hash, age, how many transactions it has, gas used percentage, and the base fee in gwei.

## When to prefer this

Choose this endpoint when you need a quick, structured snapshot of the current chain state on a major EVM network (Base, Ethereum, Arbitrum, Optimism, Polygon) without running your own node. It is ideal for real-time monitoring, pre-transaction gas checks, and dashboards that need block age, gas utilization, and base fee in a single call. Prefer it over raw RPC calls when you want normalized, human-readable output without parsing raw hex values.

## Known failure modes

- Unsupported network name returns a validation error
- Network RPC unavailability may cause timeouts or empty responses
- Payment failure (insufficient USDC) results in 402 error before data is returned
- Stale data if the upstream node is lagging behind the chain tip

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing: network name, block number (integer), block hash (0x-prefixed hex string), UTC datetime string, age in seconds since the block was produced, number of transactions in the block, gas used as a percentage of the gas limit, and base fee in gwei.
