List of api endpoints for use with reverse proxy and filtering

I wonder if there is a list of all api uri that are used by Nextcloud. It would be handy to apply some filtering on a reverse proxy.

As an example: for Matrix I have set up a synapse server, where the reverse proxy filters as:
/_matrix allowed from everywhere
/_matrix/client and /_synape only allowed from internal network (all client are in a vpn internal zone)
any other access is instantly blocked.

This puts any illegal scanning of my server like for wp vulnarabilities and other on a blocklist on the first try. Can we have something similar for Nextcloud?
