Upscale an image with Clarity Upscaler
Clarity Upscaler — creative AI upscaling that can add detail as it enlarges, steered by creativity/resemblance controls and an optional guiding prompt. 30 credits per image (typically ~60 seconds).
Asynchronous. Returns a job id (the image is not in this response). Poll GET /v1/upscales/{id} until status is succeeded — the image URL is in that response’s image_url.
