How this service works
FDA drug adverse event reports -- reactions, suspect drugs, seriousness, and a signal-based monitoring recommendation. Query: ?drug=aspirin&limit=10. If drug is omitted, defaults to `aspirin`.
Output
Returns a list of adverse event reports for the queried drug including reaction descriptions, seriousness flags, and safety report IDs, plus a signal summary with total events, serious event count, serious event rate percentage, a risk level label (e.g. 'monitor'), and a plain-English recommended action.
Example use cases
Example prompt
“Can you pull the FDA adverse event reports for ibuprofen — give me up to 20 results including the reactions, whether any were serious, and what the risk monitoring recommendation is?”
Technical details
Endpoint
GEThttps://x402-data-bazaar.vercel.app/api/fda/adverse-eventsWhen to prefer
Use this endpoint when you need structured FDA adverse event data for a specific drug, including reaction types, seriousness assessments, and an actionable risk signal — especially when you want a built-in monitoring recommendation rather than raw FAERS data. Prefer this over direct openFDA queries when you need a pre-processed signal with risk level and recommended action.
Side effects
- Drug name not found in openFDA — returns empty events array with count 0
- Missing or invalid 'limit' parameter — may return default result set or error
- OpenFDA upstream API unavailable — service returns failure or timeout
- Misspelled drug name yields no results without error message
- Rate limiting or payment verification failure returns 402 or 429
