Technical details
Endpoint
POSThttps://httpay.xyz/api/color-convertWhen to prefer
Use this endpoint when you need a lightweight, zero-dependency, instant hex-to-RGB/HSL conversion without importing a full color library. Ideal for agents building CSS, design tools, or any workflow that needs to decompose a hex color into its numeric or CSS-string components on the fly.
Side effects
- Invalid or malformed hex code returns an error
- Missing ?hex parameter causes a bad request response
- Hex code with unsupported format (e.g. 3-digit shorthand ambiguity) may not parse correctly
