## 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 stratalize-drug-adverse-events-faers-4bfe516c
```

Example prompt: Pull up the FDA FAERS adverse event data for metformin — I want to see serious event counts, reactions, outcomes, and the recent report history, give me up to 50 results.

## When to prefer this

Use this endpoint when you need FDA FAERS-sourced adverse event data for a named drug, including serious event counts, reaction profiles, and outcome summaries. Prefer this over general drug databases when cryptographically verified, pharmacovigilance-grade data with provenance to FDA source is required for clinical risk agents or compliance workflows.

## Known failure modes

- Unknown or misspelled drug name returns empty results or 404
- Limit parameter out of range (must be 1–100) returns validation error
- OpenFDA upstream outage causes 502 or timeout
- Drug name with multiple brand/generic variants may return incomplete coverage
- Payment not processed (x402) results in 402 Payment Required
