## 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-nutrition-compare-02a0b7a2
```

Example prompt: Compare magnesium glycinate vs magnesium citrate for me — I want to know the differences in absorption, clinical evidence, and which one is better for sleep and muscle recovery.

## When to prefer this

Use this endpoint when a user wants a structured, evidence-backed side-by-side comparison of two nutritional items (foods, supplements, or nutrients). Prefer this over a general nutrition lookup when the user explicitly wants to choose between options or understand relative differences supported by clinical literature.

## Known failure modes

- Unknown food or supplement name returns empty or partial result
- Ambiguous query with multiple interpretations may return generic comparison
- PubMed lookup timeout may reduce clinical evidence depth
- Language code not supported may fall back to English
- Rate limiting or payment failure returns 402 with payment required header
