So pleased to see Open Banking doing what it was intended to do : https://shkspr.mobi/blog/2020/10/unofficial-moneydashboard-api/ (by @Edent)
@Edent we proposed direct access for the customer in the original report, but I can absolutely understand why that's not been a big focus of the standard that's emerged; security is hard, and the API could be easily subverted to use customer access as an attack vector.
