🇬🇧Financial Services in United Kingdom

68 financial services providers in United Kingdom, publishing 163 APIs.

68 providers 163 published APIs 1193 indexed documents

Financial Services in United Kingdom — 68 providers on the APIs.io network sit in both cohorts, and between them they publish 163 indexed APIs.

53 of the 68 publish at least one machine-readable API; 15 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 developing, 19 thin, 9 emerging, 7 minimal, and 2 strong.

Leading by rating: Smart Pension, Algbra, Yapily, first direct, The Bank of London, Weatherbys Bank, and 62 more.

Country membership is exact-tag only. A provider lands in United Kingdom when one of its own top-level tags names the country — there is no headquarters signal on the country axis, unlike the region axis which reads tag, provider-name pattern, and stated HQ. So this cell is a floor, not a census, and it understates by construction — a financial services company headquartered in United Kingdom that never tags itself is counted nowhere on this axis. The region cuts read the wider signal set and will generally hold more.
