## 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 whatchuneed-drug-information-lookup-442b23c0 -d '<json body>'
```

Example prompt: Can you look up drug information for metformin, including its description, generic name, and any safety warnings?

## When to prefer this

Use this endpoint when you need quick structured drug information — description, generic name, and warnings — without building a full healthcare database integration. Ideal for AI agents that need to answer patient or user questions about medications in a pay-per-call, no-subscription model via x402 protocol.

## Known failure modes

- Drug name not found in database — may return empty or null fields
- Misspelled drug name may yield no results or incorrect match
- Brand names vs generic names may not always resolve to the same record
- Missing required 'name' field returns a validation error
