## 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 nexusapi-health-macros-lookup-e7ce905a -d '<json body>'
```

Example prompt: What are the macros for 100g of grilled chicken breast — I need the calories, protein, carbs, and fat breakdown for my meal plan?

## When to prefer this

Use this endpoint when an AI agent needs quick per-call nutritional macro data without maintaining an API key subscription. Ideal for pay-per-use dietary lookup scenarios within applications that already support x402 USDC micropayments on Base.

## Known failure modes

- Unrecognized food item returns empty or null results
- Vague or ambiguous query may return generic or irrelevant macro data
- Network timeout or service unavailability returns 5xx error
- Payment failure in USDC returns 402 error requiring retry with valid payment
- Malformed query string may return 400 bad request
