United Kingdom & Ireland

UK and Republic of Ireland — England, Scotland, Wales, Northern Ireland, plus Ireland.

98 providers 294 APIs

United Kingdom & Ireland on the APIs.io network surfaces 98 providers mapped to this sales region — together publishing 294 indexed APIs.

Notable providers include Wordnik, Words API, Yapily, Octopus Energy, HMRC UK Tax Authority, TransportAPI, and 92 more — each profile links out to that provider’s APIs, capabilities, schemas, and governance artifacts.

Related regions by shared providers: North America and Africa. Browse every sales region at regions.apis.io.

Region mapping is derived from provider tags and provider-name pattern matching — it surfaces what is explicitly signalled in the structured data and intentionally does not infer further. Many providers operate across multiple regions; cross-listings are expected.

About this region

APIs based in or primarily serving the United Kingdom and Republic of Ireland. Strong concentration in open banking, fintech, RegTech, and the broader financial-services API surface — driven in part by the FCA’s open-banking mandate.
