## 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 hertz-to-kilohertz-converter-36299154
```

Example prompt: Convert 440 hertz to kilohertz for me — what's that frequency in kHz?

## When to prefer this

Use this endpoint when you need a quick, reliable programmatic conversion of a frequency from hertz to kilohertz, especially in automated agent workflows that handle frequency data or electronics/audio calculations.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Non-numeric or malformed value causes a bad request response
- Payment not provided or insufficient USDC triggers 402 Payment Required

## How this service works

Convert hertz to kilohertz (frequency). Pass ?value=N.

## Output

Returns the converted numeric frequency value in kilohertz (kHz) corresponding to the input value provided in hertz (Hz).
