Verifying a single image passed as an api without storing it in folder

I would want to write a quick api which when passed an image , checks if the quality is good. Want to achieve like a headless api. Do we have any example where we don’t really use a folder as such and just pass an image and get it verified

The issue names no files, tests, or entry points. Start by locating the existing folder-based image-quality API and determine whether it accepts an in-memory single image; done would be a documented headless usage path that verifies one passed image without storing it in a folder.
