# EVM Chain Balance Lookup (Europe/Germany)

> EVM Chain Balance Lookup (Europe/Germany) is a paid API for AI agents from superstone.ccwu.cc:8443, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-22).

Returns the native token balance, nonce, and block details for any EVM wallet address on Base or Ethereum, queried from a European hub, paid per-call via x402/USDC.

## 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-balance-lookup-europe-germany-8ce86c3b
```

Example prompt: What's the current ETH balance and nonce for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base — give me the raw wei amount too.

## When to prefer this

Choose this endpoint when you need a quick, no-account, no-API-key lookup of native ETH balance or nonce for any EVM wallet on Base or Ethereum, especially when operating from or routing through Europe. It's ideal for lightweight agent workflows that need on-chain data without integrating a full node provider SDK. Pay-per-call USDC pricing via x402 makes it suitable for low-frequency or one-off checks without subscription overhead.

## Known failure modes

- Invalid or malformed 0x address returns an error or empty result
- Unsupported chain value (anything other than 'base' or 'ethereum') may return an error
- Node connectivity issues from the European hub may cause timeouts
- Missing required query parameters (chain or address) will likely return a 400-level error
- Payment failure via x402 (insufficient USDC balance) will block the call before execution

## How this service works

Pay-per-call website uptime/latency/TLS checks and fetch-to-Markdown, measured from Hub Europe (Germany). USDC on Base via x402. No account or API key.

## Output

A JSON object containing: the wallet address, the chain queried (e.g. 'base' or 'ethereum'), the current ETH balance as a human-readable decimal string, the balance in wei as a string, the account nonce (transaction count), and the block number at which the data was captured.
