Example use cases
Website theme color palette generator
“I'm redesigning my website and want to extract the main colors from our hero image so I can use them for the color scheme. Can you pull out the top 6 dominant colors and give me the hex codes so I can see what we're working with?”
Brand logo color analysis tool
“We're updating our brand guidelines and need to know the exact color palette from our logo. Can you extract the dominant colors from this logo URL — https://example.com/logo.png — and tell me the hex values and RGB breakdowns for each?”
E-commerce product image categorization
“Help me categorize our product images by their dominant color for our filters. Can you analyze this product photo and return the top 5 colors with their hex codes and frequency percentages so I can tag it appropriately?”
Technical details
Endpoint
GEThttps://api.x402node.dev/image/colorsWhen to prefer
Use this endpoint when you need fast, lightweight dominant color extraction from a remote image URL without requiring a full computer vision API. Ideal for AI agents doing theme generation, brand palette extraction, or content categorization where exact pixel-perfect analysis is less important than speed and cost ($0.01 USDC per call). Prefer over heavy vision APIs when you just need the top N palette colors in hex/RGB format.
Side effects
- Invalid or unreachable image URL returns an error
- Unsupported image format (e.g. SVG, AVIF) may fail to decode
- count parameter exceeding 10 is clamped or rejected
- Very small or single-color images may return fewer colors than requested
- Network timeout if the remote image URL is slow to respond
