I quite liked the bunq API to work with (https://doc.bunq.com), but I wasn't really happy with their 7.99€/month pricing. In the past they also required a fixed IP, which wasn't really great for hobby projects.
A decent wrapper around multiple bank APIs seems to be figo (http://docs.figo.io/v3/index.html), the API looks good but I'm not sure about the pricing.
What do you mean by "this"? I'm in Europe and all my bank accounts are very "closed", as in really difficult to build an API on. Good for security but hopeless for anything else like expense tracking.
They do offer CSV export, not even sure if that's in any standardised way.
The most promising thing seems to be the API standard developed by the "Berlin Group" https://www.berlin-group.org/psd2-access-to-bank-accounts with quite a lot of banks being a member.
