Upcoming FDA drug-approval (PDUFA) decision dates for US-listed biotechs — a forward catalyst calendar extracted from primary SEC 8-K/6-K filings, every date grounded in a verbatim filing quote and cited to its EDGAR accession. The difference from other catalyst feeds: each date is scored against the actual FDA decision, so accuracy is a public, auditable track record (median 1-day error) — verify accuracy AND coverage free at GET /v1/accuracy before you pay. Priced flat per request.
