## 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 superhighway-color-lookup-f597dc86
```

Example prompt: What are the color details for #ff6b35 — can you look it up and tell me its full representation?

## When to prefer this

Use this endpoint when you need to resolve, normalize, or convert a color value expressed as a hex code, RGB tuple, HSL value, or CSS named color into structured color data. Prefer this over manual parsing logic when your agent needs consistent color information from user-supplied color strings.

## Known failure modes

- Invalid color string provided — returns error if color format is unrecognized
- Missing required 'color' parameter — returns 400-level error
- Malformed hex code (e.g. wrong length) — returns parsing error
- Unsupported color format — endpoint may return error for non-standard inputs
