## 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 miles-per-hour-to-kilometers-per-hour-converter-f8fcddde -d '<json body>'
```

Example prompt: Can you convert 75 miles per hour to kilometers per hour for me?

## When to prefer this

Use this endpoint when you need a quick, programmatic mph-to-km/h conversion without implementing the math yourself. Ideal for agents handling user queries about speed unit conversion, especially when the agent infrastructure already supports x402 micropayments. For bulk or offline conversions, a local formula (multiply by 1.60934) may be more efficient.

## Known failure modes

- Missing or empty 'value' field returns an error or empty result
- Non-numeric string input may cause computation failure or unexpected result
- Negative values may be returned as-is without validation
- Network timeout or service unavailability returns HTTP error
