Upcoming FDA drug-approval (PDUFA) decision dates for US-listed biotechs — a forward catalyst calendar from primary SEC 8-K/6-K filings, every date grounded in a verbatim filing quote, cited to its EDGAR accession and later scored against the actual FDA decision. Use when you need the next 1-365 days of binary FDA events, whole feed or one ticker. Verify accuracy AND coverage free at GET /v1/accuracy before you pay. Flat price per request.
