Fidel is a banking API aggregator: one integration model so apps can reach many institutions with user consent. We list about 3 institutions in this directory; your app’s real coverage can still differ by product and market. For a simple mental model, Fidel is like a power strip for financial data: many banks share one interface, and your product plugs in once.

Fidel FAQ

Fidel is an open banking API aggregator headquartered in GB. It provides banking API connectivity through a single integration, so apps can reach many banks with the customer's consent instead of building one connection per bank.

Open Banking Tracker lists 3 institutions reachable through Fidel. Real coverage can differ by product, market, and individual bank, so use the supported-banks table on this page and confirm specific institutions in Fidel's own documentation.

Fidel focuses on account data (AIS) rather than payment initiation. For pay-by-bank you would pair it with a PIS-licensed provider; check Fidel's current product list to confirm.

Fidel pricing is only partly published: Self-serve API key + sales. A free developer sandbox is available to test before you commit.
