# EVM Chain Status

> EVM Chain Status is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-15).

Returns real-time network status for 12 EVM chains including block height, gas price, base fee, suggested priority fee, node client version, and sync status.

## Facts

- Endpoint: POST https://api.vextorium.com/v1/evm-chain-status?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/evm-chain-status-c0b12ca5
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_knbVtVNWTbcol0LXmXcRy

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 evm-chain-status-c0b12ca5 -d '<json body>'
```

Example prompt: What are the current gas fees and block status on Base right now — give me the base fee, suggested priority fee, and whether the node is synced?

## When to prefer this

Use this endpoint when you need real-time EVM chain status — gas prices, block height, node health — across any of 12 supported chains (Base, Ethereum, Arbitrum, Optimism, Polygon, BNB, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain). Prefer this over raw RPC calls when you need a simple HTTP API without managing Web3 infrastructure.

## Known failure modes

- Unsupported network name returns validation error
- Temporary RPC node unavailability may return null fields
- Network congestion may cause slightly stale block data
- Missing or malformed 'network' field defaults to Base chain

## 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

Returns a JSON object with: network name, chain ID, current block number, block age in seconds, gas price in gwei, base fee in gwei, suggested priority fee in gwei, node client version string, sync status (boolean), and native currency symbol.
