## 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 openfda-recalls-adverse-events-api-d6398fae
```

Example prompt: Search the FDA openFDA database for the 10 most recent drug recalls and show me the recalling firm, classification, and reason for each.

## When to prefer this

Use this endpoint when you need raw FDA recall or adverse-event data for drugs, medical devices, or food products sourced directly from openFDA with structured classification and firm details. Prefer this over the sibling multi-agency consumer recall endpoint when you specifically want FDA data with openFDA's Lucene query syntax and need the recall/event distinction.

## Known failure modes

- Invalid product type value (not drug/device/food) returns a 400 error
- Invalid report type (not recall/event) returns a 400 error
- Search query with unsupported Lucene syntax may return no results or an error
- Limit value out of range may be rejected
- openFDA upstream unavailability may cause 502/503 errors
- Payment not processed or invalid x402 header returns 402 Payment Required
