Use it when you need a wallet's live ETH and USDC balance on Base or Ethereum, or need to know whether an address is a contract or an EIP-7702 delegated account (for example before sending funds). Also returns code size and nonce. Read live from public RPC nodes at the latest block. Never charged for errors: we settle the payment only after a successful answer.
