# EVM Chain Balance Lookup (Hub Europe, Germany)

> EVM Chain Balance Lookup (Hub Europe, Germany) is a paid API for AI agents from dex12345.ccwu.cc:8443, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-27).

Fetches the current ETH balance and nonce for any EVM wallet address on Base or Ethereum, paid per-call via USDC on Base using x402.

## 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-hub-europe-germany-5ce61d3e
```

Example prompt: What's the current ETH balance and nonce for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base?

## When to prefer this

Choose this endpoint when you need a no-account, no-API-key balance lookup for a Base or Ethereum wallet address, billed at $0.002 USDC per call via x402. Ideal for lightweight agent workflows that need on-demand EVM balance or nonce data without setting up a Web3 provider or managing RPC credentials.

## Known failure modes

- Invalid or malformed 0x address returns an error or empty result
- Unsupported chain value (anything other than 'base' or 'ethereum') causes a validation failure
- Payment not processed via x402 (missing or invalid USDC payment) results in HTTP 402
- Node latency or downtime for the target chain may cause timeouts
- Rate limits could apply if the x402 payment gateway is congested

## 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

Returns a JSON object with the wallet's ETH balance expressed in both ETH (decimal string) and wei (integer string), the current nonce, the block number at which the balance was recorded, the chain name, and the queried address.
