## 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 kihustle-calorie-calculator-e06d7636 -d '<json body>'
```

Example prompt: Can you calculate the calorie needs for a 32-year-old male who is 178cm tall and weighs 82kg?

## When to prefer this

Use this endpoint when you need a simple, low-cost computation of calorie needs from basic biometric inputs (age, gender, height, weight) via a micropayment API. It is appropriate for lightweight health or fitness agents that need a quick calorie estimate without integrating a full nutrition database or complex fitness API. Not suitable when you need detailed macronutrient breakdowns, activity-level adjustments, or medically-certified dietary advice.

## Known failure modes

- Missing required fields (age, gender, height_cm, weight_kg) may result in an error or null result
- Invalid gender string values may not be handled gracefully
- Extreme or out-of-range values (e.g. negative weight) may produce unexpected results
- The response schema is vague — the actual calorie value format inside 'result' is unclear and may require parsing
- Payment failure via x402 protocol will block the request
