## 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 maxwell-x402-fda-drug-enforcement-recalls-lookup-75eec7f4
```

Example prompt: Can you search the FDA drug enforcement database for any recalls involving metformin and tell me the recall classification and reason?

## When to prefer this

Choose this endpoint when you need programmatic access to FDA drug enforcement and recall data without managing your own OpenFDA API key or rate limits. Ideal for compliance checks, pharmacovigilance workflows, or any agent that needs to verify whether a drug product or manufacturer has been subject to FDA enforcement actions. Prefer this over direct OpenFDA calls when operating within an x402 micropayment context or when you want a consistent, paid-tier proxy with reliable uptime.

## Known failure modes

- Invalid or unsupported query parameter syntax returns an OpenFDA error
- No matching records found returns an empty results array
- Rate limiting from upstream OpenFDA may cause transient failures
- Malformed request (missing required 'type' or 'method' fields) returns a 4xx error
- OpenFDA service unavailability causes upstream timeout or 5xx error

## How this service works

FDA drug recalls (enforcement reports) from openFDA, newest first: matches product, firm, reason, brand or generic name. Each recall has its number, class (I-III), status, reason, firm, dates, distribution and quantity. ?q=valsartan; 10 by default, up to 25 with &limit=. Answers are cached for up to 24 hours.

## Output

Returns JSON from the OpenFDA drug enforcement endpoint containing records of drug recalls and enforcement actions, including product description, recalling firm, recall classification (Class I/II/III), voluntary/mandated status, recall reason, distribution pattern, recall initiation date, and termination date where available.
