## 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-bmi-calculator-21fae1e6 -d '<json body>'
```

Example prompt: Can you calculate my BMI? I'm 1.75 meters tall and weigh 72 kilograms.

## When to prefer this

Use this endpoint when you need a simple, low-cost metric BMI computation from height in meters and weight in kilograms, especially in an automated agent workflow where you want a fast, pay-per-call API without managing a subscription. Not ideal if you need BMI category labels (underweight, normal, obese), imperial unit inputs, or clinical context.

## Known failure modes

- Missing height_m or weight_kg fields returns an error
- Non-numeric values for height or weight may cause a 400 or processing error
- Implausible values (e.g. height of 0 or negative weight) may produce invalid results or error responses
- Payment failure via x402 protocol returns a 402 status before computation occurs
