INFO

(We have decided to discontinue mj API in our system, and would like to introduce an anlternative. Visit Sunsetting Midjourney to learn more.)

This endpoint from PiAPI's Midjourney API extends the canvas of an upscaled image beyond the its original size while retaining the details of the original image. This endpoint corresponds to the Zoom Out tool from the official Midjourney.
