## 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-label-40c4f0a8
```

Example prompt: Pull up the official FDA label for Ozempic — I need the indications, dosage instructions, boxed warnings, and contraindications.

## When to prefer this

Use this endpoint when you need authoritative, official FDA-sourced drug label information including full prescribing details, safety warnings, and regulatory metadata. Prefer this over general web search when accuracy, regulatory authority, and structured data fields (NDC codes, pharmacologic class, boxed warnings) are required. Best for clinical reference, compliance workflows, or patient safety checks.

## Known failure modes

- Drug name not found in FDA database — returns empty results or 404
- Ambiguous name matches multiple drugs — may return unintended labels
- Non-US drugs not covered — FDA database only includes US-approved labels
- Rate limiting or service unavailability from underlying OpenFDA API
- Limit parameter out of range (must be 1-10) may cause validation error
