How this service works
Agent Wonderland is a marketplace and payment layer for agent-ready APIs. This endpoint runs FDA Adverse Events: Search FDA adverse event reports (FAERS) for any drug. Returns reported side effects, outcomes, patient demographics. Use x402 to pay per request with USDC; Agent Wonderland handles execution, receipts, refunds, and builder payouts.
Output
Returns up to 25 FDA adverse event reports for the specified drug, each containing reported side effects, patient outcomes (e.g. hospitalization, death, recovery), and patient demographic information such as age and sex.
Example use cases
Drug safety research for a new medication
“Look up FDA adverse event reports for Keytruda — give me up to 25 results so I can see what side effects and outcomes have been reported.”
Patient due diligence before starting a drug
“I was just prescribed Eliquis — can you pull up to 10 FDA adverse event reports for it so I can understand what side effects other patients have experienced?”
Pharmacovigilance signal monitoring
“Search the FDA FAERS database for Mounjaro and return 25 adverse event reports including patient demographics and outcomes.”

POSThttps://api.agentwonderland.com/x402/endpoints/fda-adverse-eventsWhen to prefer
Use this endpoint when you need structured FDA FAERS adverse event data for a specific drug, including side effect profiles, patient outcomes, and demographic breakdowns. Prefer this over general web search when you need authoritative, official FDA-sourced pharmacovigilance data in a structured format. Pair with the FDA Drug Approvals sibling endpoint for a complete drug safety picture.
Side effects
- Drug name not found in FAERS returns empty results or an error
- Limit exceeding 25 causes a validation error
- Vague or misspelled drug names may return irrelevant or no results
- Payment failure (insufficient USDC) results in a 402 error and no data returned
