## 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 agenttoll-drug-labels-lookup-e80866dd -d '<json body>'
```

Example prompt: Can you pull up the FDA drug label information for lisinopril — show me up to 5 results?

## When to prefer this

Use this endpoint when an agent needs structured, official FDA drug label data for a specific medication by name, especially in health, pharmaceutical research, or compliance contexts. Prefer this over general web search when authoritative, structured label data is required. At $0.03/call it is cost-effective for per-drug lookups.

## Known failure modes

- Drug name not found in FDA database — returns empty data array with count 0
- Invalid input types (e.g. non-integer limit) — likely returns validation error
- Payment failure via x402 — request rejected before processing
- Rate limiting or API unavailability — upstream FDA API timeout or error
- Misspelled drug name returns no results or unrelated labels
