How this service works
Create a centered square thumbnail of an image at a given size.
Output
Returns a centered square thumbnail image of the specified size, cropped from the center of the original image. The output is the processed image data (likely binary or a URL) representing the square-cropped, resized version of the input.
Example use cases
Product catalog thumbnail generation
“Take this product photo at https://shop.example.com/images/sneaker.jpg and make a centered square thumbnail at 300 pixels for the catalog grid.”
Profile picture square crop
“I need a 128x128 square thumbnail of this portrait photo https://mysite.com/users/avatar.png — make sure it's centered.”
Social media preview image
“Can you create a 512-pixel square thumbnail from https://blog.example.com/hero.jpg so I can use it as a social media card image?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/image-thumbnailWhen to prefer
Choose this endpoint when you need a quick, cost-effective centered square thumbnail from a remote image URL with minimal configuration — ideal for uniform catalog grids, profile avatars, or any context requiring consistent square aspect-ratio images. Prefer it over general image conversion endpoints (also available on 24K Labs) when the square-crop-and-resize behavior is specifically needed.
Side effects
- Invalid or inaccessible image URL returns an error
- Unsupported image format may cause processing failure
- Very large images may time out or be rejected
- Missing required size parameter returns a validation error
- Payment failure or insufficient USDC balance prevents execution
