## 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-bmi-calculator-3585a774 -d '<json body>'
```

Example prompt: Can you calculate my BMI? I'm 5 feet 10 inches tall and weigh 175 pounds.

## When to prefer this

Use this endpoint when an agent needs to quickly compute a user's Body Mass Index without maintaining any state or requiring user accounts. Ideal for health and wellness workflows where pay-per-call USDC pricing is preferred over API key management.

## Known failure modes

- Missing height or weight inputs returns an error
- Invalid or non-numeric values for height/weight cause a bad request response
- Units mismatch (e.g., mixing metric and imperial without specifying) may yield inaccurate results
- Extreme or physiologically implausible values may return an error or unexpected classification
