API to fetch transactions of financial institution accounts, integrating with many banks?

Constructing an app during which such a technical functionality is required:

The person provides a checking account to the system, performs authorization required by the middleware API Within the background, the system periodically fetches transactions carried out in that checking account. The necessary attributes of transactions: timestamp, information about cost receiver (firm identify + having an organization license plate can be a significant main plus), cost worth, forex The person doesn't have to carry out any repetitive authorizations

The audience is Europe, so have to help as many EU banks as potential.

Can anyone advocate such an API? Simply inform me the names of the businesses, and I'll examine if it suits me.
