## 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 x402-image-tools-color-palette-extraction-cb8cb1af
```

Example prompt: Can you extract the top 5 dominant colors from this image — https://example.com/photo.jpg — and give me each one as a hex code and RGB value along with how much of the image it covers?

## When to prefer this

Choose this endpoint when you need structured color data (hex, RGB, share) from a remote image URL for use in theming, palette generation, or color-based search indexing. It is purpose-built for color extraction and returns richer metadata (average color + per-color share) than generic image analysis APIs. Prefer it over general vision APIs when you specifically need color palette output without object detection or captioning.

## Known failure modes

- Invalid or inaccessible image URL returns an error
- Image exceeds 20 MB or 40 megapixel limit
- Unsupported image format (only JPEG, PNG, WebP, AVIF, GIF, TIFF, SVG accepted)
- Count parameter outside 1-10 range causes validation error
- Network timeout fetching the remote image
- Payment failure or insufficient USDC balance blocks the request

## How this service works

The dominant colors of an image with their share of it, and its average color, as hex and RGB, for palettes, theming and search.

## Output

A JSON object containing an array of dominant colors (each with hex string, RGB array, and share as a decimal fraction) and the overall average color as a hex string. For example: {"colors":[{"hex":"#2f2a22","rgb":[47,42,34],"share":0.31}],"average":"#7a6b55"}.
