Overview
Use when an agent must see who a Base wallet deals with: counterparties ranked by ERC-20 transfers, earliest inbound sender in the window, wallets the same EOA funder also sent tokens to, tokens moved. Input: address, optional hours (1-24, default 6), limit. Output: JSON counterparties with own labels (contract/EOA, known token, v4 PoolManager), first funder, shared funder. ERC-20 only, no native ETH. Example: ?address=0x92256Af59E7B98f9f25e445A869b1170DE476c26
