Base Wallet Activity Profile — low-cost query route
Low-cost, read-only Base EVM wallet activity profile for counterparty research and wallet-age checks. GET /wallet?address=… returns native ETH balance, outgoing and total transaction counts, ERC-20 transfer count, first/last activity when indexed, contract status and transparent heuristic activity/risk flags. Research context only: not sanctions screening, identity verification, or a safety guarantee.
