# EVM Chain Status (Multi-Network)

> EVM Chain Status (Multi-Network) is a paid API for AI agents from biosfera.46-62-215-147.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-30).

Returns a live snapshot of an EVM chain including chain ID, latest block number, block age in seconds, current gas price, and base fee in gwei for one of five supported networks.

## Facts

- Endpoint: GET https://biosfera.46-62-215-147.sslip.io/o/evm-status?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/evm-chain-status-multi-network-1d31aad4
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_NiTSz_TWzwWwnzvv3gcTa

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-multi-network-1d31aad4
```

Example prompt: What's the current gas price and latest block number on Arbitrum right now?

## When to prefer this

Use this endpoint when you need a quick, reliable, read-only snapshot of current EVM chain state — especially gas pricing and block freshness — across Base, Ethereum, Arbitrum, Optimism, or Polygon in a single call. Prefer it over direct RPC calls when you want a managed, cost-predictable, pre-batched response without managing your own node connections.

## Known failure modes

- Invalid or unsupported network name returns an error — only 'base', 'ethereum', 'arbitrum', 'optimism', 'polygon' are accepted
- Missing required 'network' query parameter causes a 400-style error
- Upstream public RPC node timeout or unavailability may cause delayed or failed response
- Payment failure (x402) if USDC balance is insufficient for the $0.001 per call fee

## How this service works

Use when you need a live snapshot of an EVM chain: chain id, latest block number and its age in seconds, current gas price and base fee in gwei. Covers Base, Ethereum, Arbitrum, Optimism and Polygon in one batched read-only call to public RPC.

## Output

A JSON object containing the chain ID, latest block number, block age in seconds (how long since that block was mined), current gas price in gwei, and current base fee in gwei for the requested network.
