title: How to make a large file accessible to external APIs?
body: <p>I'm new to webdev, and I have this use case where a user sends a large file (e.g., a video file) to the API, and then this file needs to be accessible to other APIs (which could possibly be on different servers) for further processing.</p>
  <p>I'm using FastAPI for the backend, defining a file parameter with a type of <code>UploadFile</code> to receive and store the files. But what would be the best way to make this file accessible to other APIs? Is there a way I can get a publicly accessible <code>URL</code> out of the saved file, which other APIs can use to download the file?</p>
