Follow the quickstart guide to get your own API Key.

The Upscale API can enlarge input images by a specified scale, delivering results of higher quality compared to traditional upscaling methods.

This API supports input images up to 2048x2048 resolution and output images up to 4096x4096 resolution. When the input resolution exceeds 2048, the scale can only be 2.
