What is the best way to get balance of large amount of addresses? I tried to use APIs from different providers, but they are limiting the requests. Is there any APIs that give premium service without limiting requests?

Or maybe should I run full node, and use it? If yes, how I'm using the full node to get the addresses balances? I'm using Runy on Rails.

Thanks.
