## 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 color-agentutil-net-f0c1c690 -d '<json body>'
```

Example prompt: Convert the color #FF5733 to both RGB and HSL for me.

## When to prefer this

Use this endpoint when you need to translate a color value from one CSS/design format to another — for example converting a designer's hex code into RGB for CSS use, or into CMYK for print. Supports all common web and print color models in a single call.

## Known failure modes

- Unrecognized color string (e.g. typo in CSS name or malformed hex) returns a 4xx error
- Unsupported target format value returns a validation error
- Empty or missing color field returns a 400 bad request
