## 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 us-fda-open-data-drug-adverse-events-recalls-labels-56bc32c4
```

Example prompt: Search the FDA database for adverse event reports related to metformin and return the top 5 results.

## When to prefer this

Use this endpoint when you need structured, authoritative pharmaceutical safety data directly from the US FDA — specifically for adverse event reports, drug recalls, or official drug labels. Prefer this over general web search when you need machine-readable, regulatory-grade drug data. Best for compliance checks, pharmacovigilance, drug safety research, or verifying recall status of a medication.

## Known failure modes

- Missing or invalid 'kind' parameter returns an error or empty response
- Drug name not found in FDA database returns zero results
- Rate limiting from underlying openFDA API causing failures
- Malformed query string resulting in API rejection
- Limit parameter exceeding FDA API maximums
