api.biotechcatalystsentinel.com
Change stream for PDUFA dates a company put in an SEC filing: every set, extension and resolution of every tracked catalyst, with the outcome (approval or CRL), the filing quote and its EDGAR source, as a since-cursor feed. Use when you mirror those disclosed dates and need changes as they land, not a snapshot. Accuracy and coverage are free at GET /v1/accuracy. Flat price per request.
