What is the best way to view BTC wallet balance?

Question

Python

I wrote a program to view the BTC balance, but the implementation is not at all optimized. Now there are two options:

• Leave the program as it is, but you need to add a proxy all the time due to error 429 (such as protection from DDos)
  
• Or advise some API or library for checking balances
  

Answer 1

You can use public electrum servers , but if you need mass analysis, then collect the data yourself using the official wallet and analysis script.
The simplest thing is to request a utxo dump once, and then for each block collect information on transactions and update balances in your database

Answer 2

We raise our btc node
