To connect to a specific node, use this in the console:

Code:

addnode 1.2.3.4 add

(Make sure to replace 1.2.3.4 with the node address.)

You can also add the following line/s to your bitcoin.conf file:

Code:

addnode=1.2.3.4

Additionally, you can use -addnode=<node's IP> or -connect=<node's IP> as startup parameter if you only want to connect to a specific node once.
Use -connect=<node's IP> if you only want connect to one node.

But if you don't use Bitcoin Core as your full node client, the syntax or parameter might be different.

There are lots of method/way to do it (you can check https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)), but it's not possible to do so with Bitcoin Core.

But depending on your usage, use 3rd party API such as https://chain.so/, https://blockchair.com/ or https://www.blockcypher.com/ is good idea since they offer wide-variations of API functions.

That is exactly what the JSON-RPC is designed for... however the remote node would need to be configured correctly (rpcuser/rpcpassword etc) AND allow incoming RPC connections from your IP. According to the docs, by default, it is setup to only allow processes on the local machine to connect.
