## 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 kihustle-color-contrast-checker-53280639 -d '<json body>'
```

Example prompt: Can you check if white text (#FFFFFF) on a navy blue background (#003366) has enough contrast to be accessible?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.002 USDC) programmatic check of whether a foreground/background color pair meets accessibility contrast standards, without setting up a local WCAG library or parsing complex color math yourself.

## Known failure modes

- Invalid or missing color values — returns error if background or foreground fields are not valid color strings
- Malformed hex codes or unsupported color formats may result in processing failure
- Server-side errors returning generic failure status if the service is unavailable

## Output
