UpRes
UpRes is an AI image-upscaling API offering 18 selectable models (including Real-ESRGAN, SeedVR2, and AuraSR) to enlarge images up to 8K resolution, billed through a free starter credit tier plus paid $19/$49/$299 credit packs for higher volume. A live GET against its docs host, upres.ai, returned Access-Control-Allow-Origin: *, reconfirming cors yes; the actual upscaling calls require an API key over HTTPS as already stored.
