Ask HN: Are there ways to access bank account balance? (your own)

Every time I try to work with some finance app (self made) the problem is the balance isn't real time, I have to edit it upon a purchase. One possible solution is login automation like Selenium I think? I don't know, are there any known solutions to get around this? I get the potential security risks, and this is just for myself. edit: with PayPal there is a way using one of their APIs, but I'm talking your bank account. Probably not, unless they had some convenient balance-get API.
