## 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 api-x402node-dev-b9899460
```

Example prompt: What's the HSL value of the hex color #3a86ff? I need both the CSS hsl() string and the intermediate RGB values.

## When to prefer this

Use this endpoint when you need to convert a hex color code to HSL format, especially when generating CSS stylesheets, performing color theory analysis, or needing the CSS hsl() string directly. Prefer this over manual computation when you want both the numeric HSL components and the formatted CSS value in one call.

## Known failure modes

- Invalid hex code format returns an error
- Missing or malformed input body returns a 400-level error
- Hex code with unsupported characters or wrong length fails validation
