Reverse lookup spanning multiple CUSIPs at once. Pass a comma-separated list of CUSIPs and the endpoint returns every 13F filer holding at least min_overlap of them in the requested quarter. Useful for detecting consensus baskets (e.g. 'which funds hold all 5 of these AI infrastructure names?'). Each matched fund's per-CUSIP position detail (shares + value + issuer) is echoed so callers don't need a follow-up scan. min_overlap defaults to 2 (the meaningful overlap floor); set to len(cusips) for a strict intersection. PUT/CALL option rows are filtered before counting - this is a stock-ownership signal, not derivative exposure. Optional ?quarter=<stem> selects a historical snapshot (default: newest stem in retention manifest).
