## 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-drug-recall-changes-feed-eb69ac9d
```

Example prompt: Pull all FDA drug recalls reported since 2025-01-01T00:00:00Z and show me only the most serious ones — Class I only (significance 9 or higher), up to 50 results.

## When to prefer this

Use this endpoint when you need a structured, machine-readable feed of recent FDA drug recalls filtered and scored by severity — especially for monitoring workflows, alerting pipelines, or compliance dashboards that need to detect Class I (most serious) recalls as they are reported. Prefer over manual FDA website checks or general news searches when you need structured data with significance scoring and direct source links.

## Known failure modes

- Invalid or missing 'since' date-time format returns a 400 error
- min_significance outside 1–10 range returns a validation error
- No recalls found in the window returns count:0 with an empty changes array
- Upstream FDA data unavailable may return a 503 or stale data
- limit exceeding 500 returns a validation error

## How this service works

FDA drug enforcement actions (recalls) reported since a timestamp, scored by recall class (Class I = most serious), with recalling firm, reason, and distribution. Filter ?min_significance=9 for Class I only.

## Output

A JSON object with a count, source label, and an array of change records — each containing a recall title, summary, significance score (1–10), detected timestamp, effective date, entity ID for detail lookup, and a primary-source URL for verification.
