PDUFA dates a company put in an SEC filing, not a calendar of every US-listed biotech. Each date is grounded in a verbatim filing quote, cited to its EDGAR accession, and scored against the FDA decision. Use when you need the next 1-365 days of those disclosed dates, whole feed or one ticker. Accuracy and coverage are free at GET /v1/accuracy. Flat price per request.
