Support Open Banking interfaces
Context: https://www.openbankproject.com/
There is the PSD2 regulation from the EU, which means this feature could potentially benefit a lot of end-users. There are many providers of Open Banking APIs and the regulation specifically said that banks must provide a free Open API. https://yts.yolt.com/open-banking/open-api
Yolt's API can be a good candidate to start since they provide a connection between users and the banks (to avoid implementing Open Banking APIs for different banks). Though there are also some other providers.
