| Name | Description | Schema |
|---|---|---|
base_address | Base (chain 8453) address snapshot: EOA vs contract vs EIP-7702, ETH balance, nonce, code size and native USDC balance, at the latest block. Costs $0.002 USDC on Base via x402. | typed |
base_erc20_balance | ERC-20 balance of any address for any token on Base, with symbol and decimals already applied (raw and human-readable). Costs $0.002 USDC on Base via x402. | typed |
base_token | Token facts on Base: name, symbol, decimals, total supply, contract code size, owner() and EIP-1967 proxy implementation, plus plain-language notes (upgradeable? owner renounced?). Read-only facts, no | typed |
base_tx | Human-readable summary of a Base transaction: status, block time, from/to, value, total fee (incl. L1 fee), and decoded ERC-20 Transfer events with token symbols and amounts. Handy to verify a payment | typed |
