它能做什么

Cheap, keyless on-chain reads for agents — native + ERC-20 balances, gas price, transaction status, token supply, ENS, nonce, across Base, Ethereum, Optimism, Arbitrum, Polygon. Use whenever an agent needs to read chain state without running a node or juggling RPC keys: check a wallet balance, current gas, whether a tx confirmed, a token's supply. ~$0.001/call, USDC on Base via x402, no API key, no signup.
