How this service works
FDA adverse event reports (FAERS) for a drug from openFDA, newest first: report id, date received, seriousness (death, hospitalisation, life-threatening), reactions, drugs taken and indication. ?q=metformin; 5 by default, up to 25 with &limit=. Cached for up to 24 hours. Reports are not proof the drug caused the event.
Output
Returns a JSON object with FDA adverse event records from the FAERS (FDA Adverse Event Reporting System) database, including fields such as patient reactions, drug names, report seriousness, patient demographics, and report dates. The response mirrors the OpenFDA drug/event API structure, served from a cached proxy.
Example use cases
Drug side-effect research for a medication
“Look up FDA adverse event reports for metformin — I want to know what kinds of reactions patients have reported and how many cases there are.”
Pharmacovigilance safety check
“Search the FDA FAERS database for serious adverse events reported for warfarin so I can understand its known risk profile.”
Comparing drug safety profiles
“Fetch FDA drug adverse event records for atorvastatin — I'm trying to compare the reported side effects with those of rosuvastatin.”
Technical details
Endpoint
GEThttps://api.maxwellinternational.ai/v1/openfda/drug/event?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatic access to FDA drug adverse event data (FAERS) without setting up your own OpenFDA integration, and when you want a pay-per-call model at low cost ($0.005 USDC). Prefer it over direct OpenFDA calls when operating in an x402-payment-enabled agent environment or when you need a cached, low-latency proxy rather than hitting the FDA API directly.
Side effects
- Invalid or unsupported queryParams syntax returns an error or empty results
- Drug name not found in FAERS returns zero results
- Cache miss may cause slightly slower response or stale data
- Malformed input object (missing required 'type' or 'method' fields) returns a validation error
- Rate limiting or upstream OpenFDA outage may cause failures
