Authentication

Every request takes your API key as the apiKey query parameter. Keys are managed in your account, under API Access (one active key per account; regenerate any time).

curl "https://api.biopharmawatch.com/api/v2/fdacalendar?apiKey=YOUR_API_KEY&ticker=MRNA"

Keep your key secret. It carries your plan's access and rate limit. If a key is exposed, regenerate it from your dashboard and the old key stops working immediately.

Use it in your AI assistant MCP

Connect BiopharmaWatch to ChatGPT, Claude (and Claude Code), Cursor and any MCP-compatible assistant. Add the connector URL with your API key and your AI can query every endpoint here. We help you set it up, no call needed.

One URL, your data inside any AI

Ask things like "which PDUFA dates next month carry the highest approval odds?" and your assistant answers from live BiopharmaWatch data.
