## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fda-faers-drug-adverse-event-reports-73ca7734
```

Example prompt: Can you pull up to 8 FDA FAERS adverse event reports for the generic drug metformin so I can see what reactions and serious outcomes have been reported?

## When to prefer this

Choose this endpoint when you need quick access to real FDA FAERS spontaneous adverse event reports for a specific generic drug, especially for pharmacovigilance research, clinical safety review, or patient safety queries. It is ideal for structured report retrieval rather than aggregate statistics, and when you need patient-level details (age, sex, reactions, seriousness) per report. Prefer alternatives if you need causation analysis, aggregate signal statistics, or branded drug name lookup.

## Known failure modes

- Drug name not found or no FAERS reports exist — returns empty results or 404
- Drug name parameter missing or too short (under 2 chars) — validation error
- Drug name exceeds 60 characters — validation error
- openFDA upstream outage or rate limiting — 502 or timeout
- Max parameter out of range (not 1–10) — validation or clamp behavior

## How this service works

FDA FAERS drug adverse event reports (openFDA) for a generic drug name: report ID, receive date, seriousness, patient age and sex, drugs and reported reactions. Spontaneous reports only; a report does not prove the drug caused the reaction. Up to 10 reports per call.

## Output

Returns up to 10 spontaneous FAERS report objects, each containing a report ID, receive date, seriousness flag, patient age and sex, list of drugs involved, and list of reported adverse reactions. Data sourced from openFDA; reports do not prove causation.
