Yes, take a look at the OBIE [0]. You are required to be registered/regulated as an appropriate 'Third Party Processor' (TPP) class, in this case an AISP.

Then you can use an API aggregator service such as SaltEdge, TrueLayer, Teller [1], etc. (I'm not associated with any of these). Or you can try to roll your own.
