FDA drug-approval catalyst change stream for US-listed biotechs
FDA drug-approval catalyst change stream for US-listed biotechs: every state change of every tracked catalyst — each PDUFA date as set, extended and resolved — with the real outcome (approval or CRL), the SEC filing quote and its EDGAR source, as a since-cursor delta feed. Use when you mirror the calendar and need date changes and outcomes as they land, not a snapshot. Accuracy AND coverage are free at GET /v1/accuracy. Flat price per request.
