Vintage sepia effect for old-look photos
“Apply a sepia filter to this image — https://example.com/landscape.jpg — I want that old vintage brownish look.”
Accessibility-friendly UI asset generation
“I need a desaturated version of our hero image at https://mysite.com/hero.png for a grayscale design mockup — can you convert it to black and white?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/image-grayscaleWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.002 USDC) grayscale or sepia conversion without setting up a full image-processing pipeline. Ideal for agents automating document workflows, design tasks, or content pipelines that need color-stripped image variants on demand.
Side effects
- Invalid or inaccessible image URL returns an error
- Unsupported image format may cause processing failure
- Network timeout if the source image is very large
- Missing required image input returns a 400 bad request
