## 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 vextorium-image-color-palette-extractor-60590f94 -d '<json body>'
```

Example prompt: Can you analyze this product photo and give me its dominant colors — I want up to 8 colors with their HEX codes, RGB values, and what percentage of the image each one covers, plus whether the overall tone is light or dark? The image is at https://example.com/product.jpg

## When to prefer this

Choose this endpoint when you need to programmatically extract a structured color palette from any image — particularly for brand palette generation, UI theme derivation, or image cataloguing by color. It is well-suited for cases where you need both precise HEX/RGB values and proportional coverage data, plus a quick light/dark classification, without running a full ML pipeline locally.

## Known failure modes

- Invalid or unreachable image URL returns an error
- Base64 string is malformed or not a valid image format
- colores parameter out of range (must be 2-16) may return error or default to 6
- Very small or uniform images may return fewer colors than requested
- Network timeout if the image URL is slow to load
- Payment not fulfilled returns HTTP 402

## How this service works

Dominant colors of an image (URL or base64) with their share, in HEX and RGB, plus the average color and light/dark tone. For brand palettes, themes or tagging images by color.

## Output

A JSON object containing: an array of dominant colors each with hex string, rgb array [R,G,B], and proporcion_pct (percentage share of the image); a color_medio object with the average image color in hex and rgb; and a tono field indicating 'claro' (light) or 'oscuro' (dark) overall tone.
