Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 fiona-glp-1-research-query-a9a8ca08 -d '<json body>'
```

Example prompt: What does current clinical research say about the long-term cardiovascular benefits of semaglutide in obese patients — give me up to 15 sources?

## When to prefer this

Use this endpoint when you need synthesized, cited research answers specifically about GLP-1 drugs, obesity treatments, or related clinical trials — not general medical or pharmaceutical questions. Ideal when a user needs a research-quality answer with traceable sources rather than a simple fact lookup.

## Known failure modes

- Missing required 'question' field returns validation error
- Overly broad or ambiguous question may return low-quality synthesis
- Payment failure (x402 protocol) returns 402 Payment Required before query is processed
- Rate limiting or server error may return 5xx response
- No relevant results found may return empty sources array with limited answer
