Financial Technology in United Kingdom & Ireland

105 financial technology providers across United Kingdom & Ireland, publishing 127 APIs.

105 providers 127 published APIs 789 indexed documents

Financial Technology across United Kingdom & Ireland — 105 providers on the APIs.io network sit in both cohorts, and between them they publish 127 indexed APIs.

44 of the 105 publish at least one machine-readable API; 61 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: 34 minimal, 32 emerging, 21 thin, 13 developing, 4 strong, and 1 exemplar.

Leading by rating: AlgoVoi, Super Payments, Kota, Smart Pension, Moneyhub, Algbra, and 99 more.

Region membership is derived from three explicit signals — a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. This is a map of stated headquarters, not of markets served.
