## 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 kelvin-to-rankine-temperature-converter-acf482ef
```

Example prompt: Can you convert 373.15 kelvin to rankine for me?

## When to prefer this

Use this endpoint when you need a direct, single-value kelvin-to-rankine unit conversion without implementing the math yourself. Ideal for agents handling thermodynamic calculations, scientific data normalization, or engineering workflows that use the Rankine scale (common in US engineering contexts).

## Known failure modes

- Missing or invalid ?value query parameter returns an error
- Non-numeric value provided returns a parsing or validation error
- Very large or very small values may cause out-of-range errors
- Network or service unavailability returns a 5xx response

## How this service works

Convert temperature from kelvin to rankine. Pass ?value=N.

## Output

A numeric temperature value expressed in rankine, equivalent to the input kelvin value multiplied by 1.8.
