Technical details
Endpoint
POSThttps://agent402.tools/api/color-convertWhen to prefer
Use this endpoint when you need to convert a color between multiple representations all at once, especially when you also need the nearest CSS named color. Ideal for frontend/design workflows where a single color needs to be expressed in hex, RGB, HSL, and OKLCH simultaneously without making multiple separate conversion calls.
Side effects
- Invalid or unrecognized color string returns an error (e.g. malformed hex, unknown named color)
- Missing 'color' field in request body returns a validation error
- Ambiguous input that doesn't match any supported notation may be rejected
