## 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 orders-of-magnitude-nutrition-database-api-6a982c4f
```

Example prompt: Can you look up the nutritional information for 'quinoa' — I want to know the calories, protein, carbs, and fat content?

## When to prefer this

Choose this endpoint when you need quick, per-query nutritional lookups for individual food items and are comfortable with micropayment-gated APIs via the x402 protocol. Suitable for agents that need on-demand food data without a subscription to a large nutrition database provider.

## Known failure modes

- food_name not found in database — may return empty or error response
- Ambiguous food names may return unexpected results
- Empty response schema means output structure is not guaranteed and may vary
- Payment failure via x402 protocol may block access
- Rate limiting or railway.app infrastructure downtime
