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 token balance as a human-readable decimal string (e.g. '12.5'), the raw integer balance, the token symbol, and the number of decimals used by the contract.
Example use cases
Verify DeFi wallet token holdings
“Check how much USDC the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 holds on Base — the USDC contract is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.”
Monitor treasury ERC-20 balance
“What's the current balance of token 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 (USDC on Ethereum) for our treasury address 0x1234567890abcdef1234567890abcdef12345678?”
Confirm airdrop recipient holdings
“Before we proceed, confirm whether wallet 0xAbCd1234567890abcdef1234567890AbCdEf1234 actually holds any of the token at contract 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum.”

Choose this endpoint when you need a quick, no-account ERC-20 balance lookup on Base or Ethereum and are comfortable paying $0.002 USDC per call via x402. Ideal for agents that need onchain token data without setting up an RPC provider or API key, especially in automated workflows where micropayment-based access is acceptable.
Side effects
- Invalid EVM address format returns an error response
- Unsupported chain value (not 'base' or 'ethereum') causes a validation failure
- Invalid or non-ERC-20 contract address may return zero or an error
- Payment failure via x402 results in a 402 Payment Required response
- Network or node timeout may cause delayed or failed responses
