🇬🇧United Kingdom
A global financial and fintech center.
United Kingdom on the APIs.io network surfaces 319 providers that carry a United Kingdom tag — together publishing 1257 indexed APIs.
Notable providers include Ordnance Survey, Super Payments, Moneyhub, Xoserve, Reapit, GSMA, and 313 more — each profile links out to that provider’s APIs, schemas, and governance artifacts.
Related countries by shared providers: Ireland, Sweden, Singapore, and Indonesia. Browse every country at countries.apis.io.
Country mapping is derived from the country tags providers carry — it surfaces what is explicitly signalled in the structured data and intentionally does not infer geography further. Most providers carry no country tag, so coverage is deliberately partial; many companies also operate across multiple countries, and cross-listings are expected.
