🇬🇧Banking & Open Banking in United Kingdom

95 banking & open banking providers in United Kingdom, publishing 1426 APIs.

95 providers 1426 published APIs 1427 indexed documents

Banking & Open Banking in United Kingdom — 95 providers on the APIs.io network sit in both cohorts, and between them they publish 1426 indexed APIs.

70 of the 95 publish at least one machine-readable API; 25 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 31 thin, 26 developing, 17 minimal, 13 emerging, 5 strong, and 3 exemplar.

Leading by rating: Super Payments, Moneyhub, Griffin, Modulr, The Bank of London, Sikoia, and 89 more.

Country membership reads a tag, a stated headquarters or a stated nationality. A provider lands in United Kingdom when one of its own top-level tags names the country, when its own description states a headquarters that names the country or one of its cities, or when it describes itself by nationality (“a French company”; roadmap#542, #719). Region words (“Latin American”), language uses (“French-speaking”) and a city named outside a headquarters statement are not counted, so this cell is a floor, not a census.
