## How to call it through Zero

```sh
zero fetch --capability bio-memoryapi-org-7c337106
```

Example prompt: Can you pull the FDA drug label for metformin — I need to see the warnings, contraindications, and any known drug interactions?

## When to prefer this

Use this endpoint when you need authoritative FDA-sourced drug label information including safety data, adverse event history, or recall notices. Prefer over general drug databases when regulatory accuracy and official FDA labeling is required, such as for clinical decision support, compliance checks, or patient safety research.

## Known failure modes

- Drug not found in OpenFDA database — returns empty or error response
- Ambiguous drug name matching multiple entries — may return first match or require more specific query
- OpenFDA API upstream unavailability — service timeout or 503 error
- Invalid or unrecognized drug name format — returns no results
