I was looking for something that aggregates my transaction informations across banks, and output to a database (or a csv, so I can handle it later). The point is to have this programmatically. This can be later used by the accountant.

Plaid was the go to tool for this. Unfortunately, many bank require OAuth2 now, and using Plaid with Oauth2 requires production account and jumping through a lot of hoops.

Are there anything else out there? I don't mind paying.

Currently, I just think about getting something like Mint, and then get some tool to scrape Mint.
