Use when an agent must see who is accumulating or dumping a Base ERC-20 right no
Use when an agent must see who is accumulating or dumping a Base ERC-20 right now. Input: token address, minutes (1-60, default 60), limit (1-25). Output: JSON top net buyers and sellers (net, received, sent, contract or EOA), largest transfers with tx hash, volume, mints/burns, active wallets, covered window. Busy tokens get a shorter window. Example: ?address=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed
