## 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 fahrenheit-to-kelvin-temperature-converter-8ddc3f45
```

Example prompt: What is 98.6 degrees Fahrenheit converted to Kelvin?

## When to prefer this

Use this endpoint when you need a quick, programmatic Fahrenheit-to-Kelvin conversion without implementing the formula yourself, particularly in scientific, physics, or data pipeline contexts where Kelvin is the required unit. Prefer this over general-purpose math tools when you need a dedicated, reliable unit conversion with minimal setup.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Non-numeric value passed causes a bad request or error response
- Payment failure (402) if USDC micropayment not included or insufficient
- Server-side error if value is out of expected range or malformed

## How this service works

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

## Output

A numeric temperature value expressed in Kelvin, converted from the input Fahrenheit value provided via the query parameter.
