## 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 24k-labs-image-dominant-color-extractor-a17287aa -d '<json body>'
```

Example prompt: Can you pull the dominant color palette from this product image — https://example.com/product.jpg — and give me the hex codes along with how much of the image each color covers?

## When to prefer this

Choose this endpoint when you need to programmatically extract the actual color composition of an image with exact hex codes and coverage data — ideal for design automation, brand color extraction, product tagging, or any workflow where you need quantified color dominance rather than a human description of image colors.

## Known failure modes

- Invalid or unreachable image URL returns an error
- Unsupported image format may cause processing failure
- Very low-contrast or monochrome images may return fewer palette entries
- Network timeout if image file is too large or slow to fetch
- Malformed request body returns a 400 error

## How this service works

Extract the dominant color palette from an image as hex codes with coverage.

## Output

Returns a list of dominant colors extracted from the image, each represented as a hex color code (e.g. #3A7BD5) paired with a coverage value indicating what percentage or proportion of the image that color occupies, ordered by dominance.
