## 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 primeapi-food-compare-63299463 -d '<json body>'
```

Example prompt: Compare the nutritional profiles of salmon and chicken breast — I want to know which is better for a high-protein, low-fat diet.

## When to prefer this

Use this endpoint when you need a structured side-by-side comparison of food items by nutritional content or dietary attributes, especially in a pay-per-call context without needing a dedicated nutrition API key. Prefer alternatives if you need detailed ingredient-level breakdowns or USDA-grade certified data.

## Known failure modes

- Unrecognized food name returns empty or error response
- Ambiguous query matching multiple food variants may return unexpected results
- Overly broad query may return generic rather than specific comparison data
- Payment failure (402) if USDC balance is insufficient
- Timeout if external nutrition data source is slow
