{"name":"image-expand","description":"Extends a source photo onto a larger canvas, generating realistic new background and content beyond its original edges instead of just stretching or cropping it. Send image_url with canvas_width and canvas_height, optionally original_width/original_height and original_x/original_y to place the source image within the new canvas, plus an optional prompt, negative_prompt, and seed for control. Returns the expanded image_url with its final width, height, and seed, using a commercially licensed outpainting model. Use it as an image outpainting API, AI image expansion tool, or background extender for product photos and social crops.","price":"$0.15","method":"POST","input_schema":{"properties":{"image_url":{"type":"string","description":"Source image URL to expand."},"canvas_width":{"type":"number","description":"Target canvas width in pixels. 256-4096."},"canvas_height":{"type":"number","description":"Target canvas height in pixels. 256-4096."},"original_width":{"type":"number","description":"Width of the original image within the new canvas.
