Sure, but that information today is gatekept quite well and impossible for you or me to pull or integrate without partnerships or paying up heavily. For example, plaid is a company worth 13.4b where largely all they do is log in to your financial accounts on behalf of another (usually financial) institution to scrape your account data. If you try doing that yourself, you will be blocked by the risk systems of the various banks.

Other companies like mint and byallaccounts largely did the same thing and were aquired at $170 per account and $33 per account respectively. So obviously someone is making money on keeping your data gatekept.
