Onchain Query API

Wallet snapshot on any major EVM chain: native token balance with USD value, USDC balance, transaction count (nonce), and whether the address is a smart contract or a regular EOA. One call, no RPC keys, node infrastructure or block-explorer scraping needed. Use it to check a counterparty wallet, confirm an address is funded before sending a transaction, or profile an unknown address.
