## 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 forgemesh-color-conversion-api-bf9976a7 -d '<json body>'
```

Example prompt: Convert #3a7bd5 to RGB and HSL, tell me if it's a dark color, and tell me whether I should put black or white text on top of it.

## When to prefer this

Use this endpoint when you need instant, locally-computed color format conversion and accessibility checks without relying on a design tool API. Ideal for theming engines, chart generators, or design agents that need to programmatically determine text contrast and multi-format color values from a single input color.

## Known failure modes

- Invalid color string (not a valid hex or rgb() format) returns an error
- Missing 'color' field in request body returns a validation error
- Malformed hex (e.g. wrong number of digits) returns a parsing error

## How this service works

Color conversion API: any hex or rgb() color to hex, RGB, and HSL plus is-it-dark detection and the accessible text color (black or white) to place on top of it. For theming, chart, and design-generation agents. Instant, computed locally.

## Output

Returns the input color expressed as hex, RGB components, and HSL values, plus a boolean indicating whether the color is dark, and the recommended accessible text color (either black or white) to overlay on it.
