Is it possible to retrieve a list of files in a JSON format from a NFS URL

I have a NFS location that is not managed by me and looks like this https://ftp.mozilla.org/pub/firefox/releases/52.0/

When you access the address with a browser, curl or wget, you get of course a HTML page.

I was wondering if it's possible to get the list of files in a JSON format response without doing anything on the NFS side, e.g., like send the request to the URL with different headers.

Thanks.
