The API simulates a Upscale button click on the Midjourney channel. A completed image will return an array of buttons which you can subsequently invoke on the image. These buttons are dynamic and a list of buttons you can press are included in every image completion. In boost mode, which optimized generation speed like CDN uploading and progress handling. The only change is to use the new endpoint, and parameter and reponse are exactly the same to the original button API.
