Inspects one Base mainnet address
Inspects one Base mainnet address: whether it holds contract code and how large, whether it is an EIP-1967 upgradeable proxy (and its implementation address), EIP-7702 delegation, and which standards it reports or behaves like (ERC-165, ERC-721 NFT, ERC-1155, ERC-20). Useful for knowing what kind of contract an agent is about to interact with or approve. Read-only. Not charged for an invalid address or when Base can't be reached.
