Check for a token balance

[Tempest777]

Is this something I could do with Infura? I have read docs and see how I could get the actual balance of ETH, but I need to check both ETH balance and ERC-20 tokens. I don’t need the actual balances but just to check if any ERC-20 tokens exist in the wallet. Thanks.
