How this service works
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.
Output
An array of PDUFA catalyst event objects, each containing event_type (date_set, extension, approval, CRL), drug_name, company, ticker, new_date, outcome, a verbatim SEC filing quote, and an EDGAR source URL, plus result metadata and an error field. The response represents only events newer than the provided since cursor, enabling efficient incremental polling.
Example use cases
Example prompt
“Pull the latest FDA PDUFA catalyst events from BiotechCatalystSentinel that have come in since event ID 4820 — give me up to 200 results, including any new dates set, extensions, and final outcomes like approvals or CRLs with their SEC filing sources.”
Technical details
Endpoint
GEThttps://api.biotechcatalystsentinel.com/v1/eventsWhen to prefer
Use this endpoint when you need incremental, cursor-based access to the full history and live stream of FDA PDUFA catalyst events — including past resolutions with verified outcomes and SEC-sourced evidence — rather than just a forward-looking calendar snapshot. Ideal for agents that need to poll for changes, backfill historical event data, or build audit trails of drug approval decisions with source citations.
Side effects
- Invalid or negative since cursor returns 400 error
- limit out of range (below 1 or above 500) returns 400 validation error
- No new events since cursor returns empty data array with 200 status
- Payment not provided or rejected returns 402 Payment Required
- Rate limiting or abuse returns 429 Too Many Requests
- Service unavailability returns 503 with error message
