## 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 nutripulse-supplement-nutrient-interactions-checker-1fb21981
```

Example prompt: Can you check if there are any known interactions between magnesium glycinate, vitamin D3, and zinc — I want to know if it's safe to stack all three together, ideally with clinical sources?

## When to prefer this

Choose this endpoint when a user needs evidence-based analysis of supplement or nutrient interactions, especially when clinical literature grounding (PubMed) is important. Prefer over generic chatbot responses when safety-critical stacking decisions are involved or when a health coach, dietitian, or AI health agent needs citable references.

## Known failure modes

- Missing or unrecognized supplement names — returns empty or error response
- Obscure compound combinations with no PubMed data — low-confidence or null results
- Rate limiting or payment failure via x402 — 402 or 429 status code
- Invalid language code in ?lang= parameter — may default to English or return error
- Network timeout on Vercel edge — intermittent 504 errors
