bitcoind – Scan ports for my onion bitcoin node and RPC calls

I’m getting to work my first bitcoin node, it is running P2P through Tor network.

1: How can it be scanned? how can I see if its exposing any port, or port 8333?

2: How can I make RPC calls through Tor?…. maybe this is not the best way because of security for the RPC API and calls in plain data…

Thank you!
