But monzo card is still just prepaid debit card. You don't get a current account.
That might change later this year when they roll out current accounts but for now it's just simple prepaid/travel debit card with mobile app.
Also not sure they have switched from WireCard yet? Last time I heard they have not switched all of their existing users to their own platform but perhaps they managed the transition already?
Unfortunately the Bunq API requires a fixed IP address which means I can't use it with my non-cloud banking software from my (dynamic IP) home connection.
Teller is not a bank itself though. I believe it started as a wrapper around banks' private APIs, not sure whether that's still the case.
