## 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 saylor-innovations-data-desk-fda-drug-label-lookup-75a17671
```

Example prompt: Can you pull the FDA drug label for metformin — specifically the boxed warning, contraindications, and dosage instructions?

## When to prefer this

Choose this endpoint when you need structured, official FDA label data for a specific drug by name — including safety-critical sections like boxed warnings, contraindications, and adverse reactions — without parsing raw FDA documents yourself. Ideal for healthcare, pharmacy, or compliance workflows where authoritative label text is required. Prefer over general web search when you need clean, structured JSON output tied to a specific drug's approved label.

## Known failure modes

- Drug name not found in FDA database — returns empty or null fields
- Ambiguous drug name matching multiple products — may return data for unexpected formulation
- Truncated label text if excerpt is very long
- Network or upstream OpenFDA API unavailability
- Payment required (x402) if USDC micropayment not attached to request

## How this service works
