Use when you need a wallet's token balances on several chains in one call: native coin plus USDC, USDT, DAI, WETH, WBTC/cbBTC on Ethereum, Base, Arbitrum and Polygon. Pass address (0x or an ENS name like vitalik.eth, resolved on Ethereum) and optional chains. Exact on-chain amounts with block numbers; a chain that fails is listed in errors, never shown as zero. No USD prices. $0.003 per call (USDC or USDT). Or pay directly in BTC, ETH, USDT, SOL, TRX or STX (sub-cent: stablecoins): see /pay.
