Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/image-thumbnailWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.003 USDC) serverless thumbnail crop that centers and squares an image without needing a full image editing pipeline. Ideal for agents generating consistent square previews for product grids, avatars, or social media assets from arbitrary source URLs. Prefer over full image conversion endpoints when the specific need is a centered square crop at a fixed size.
Side effects
- Invalid or unreachable image URL returns an error
- Unsupported image format may cause processing failure
- Requested size too large or too small may be rejected
- Network timeout if source image server is slow
- Malformed request body missing required fields returns 400
