Return API /previews call with location instead of content

I would like to show previews to the user via the /get_preview call, without downloading/processing each preview via the server. To do so, I now need to point the user to https://content.dropboxapi.com/2/files/get_preview with authentication. But that means that the users are able to obtain the access_token if they look at the GET/POST request.

So I was wondering, will it be possible to request for a preview url via an API call with authentication which will return a temporarily location of the preview (comparable with the /2/files/get_temporary_link call)? When that is possible, I can just redirect the user to this location directly without authentication.
