## 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-comparison-cf960045 -d '<json body>'
```

Example prompt: Can you compare metformin and glipizide for me — I want to know the differences in how they work, their side effects, and any interactions if taken together?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call drug comparison without maintaining a subscription to a pharmaceutical database. Ideal for agents assisting with medication research, patient education, or clinical support where comparing two or more drugs on demand is needed. Prefer this over general LLM queries when you want a structured, medically-oriented comparison output.

## Known failure modes

- Unknown or misspelled drug name causes incomplete or empty comparison
- Vague input without specific drug names returns generic or unhelpful response
- Network or upstream API timeout returns error status
- Insufficient input detail may result in partial comparison only
- Payment failure via x402 protocol results in 402 response before processing
