## 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 geekvault-dominant-colors-extractor-1c6af774 -d '<json body>'
```

Example prompt: Can you analyze this image and tell me what the dominant colors are, with their hex codes?

## When to prefer this

Choose this endpoint when you need a fast, no-signup, pay-per-call dominant color extraction from an image without subscribing to a full computer vision platform. Ideal for lightweight design tooling, automated catalog tagging, or one-off palette extraction tasks where you want to pay $0.003 USDC per call via x402 rather than committing to a monthly API subscription.

## Known failure modes

- Invalid or malformed image file returns an error
- Empty or missing 'file' field causes a 400 bad request
- Unsupported image format may result in processing failure
- Very large image files may time out or exceed size limits
- Non-image binary data passed as file will fail analysis

## How this service works

Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.

## Output

Returns an array of dominant colors, each with a hex code string (e.g. '#FF5733') and an integer pixel count indicating how many pixels in the image correspond to that color, ordered from most to least dominant.
