Sales region

Central & Eastern Europe

Poland, Czech Republic, Hungary, Romania, the Balkans, and the post-Soviet states.

69 providers 423 APIs

Central & Eastern Europe on the APIs.io network surfaces 69 providers mapped to this sales region — together publishing 423 indexed APIs.

Notable providers include Infobip, ZnanyLekarz, Braiins, Mews, Kontomatik, University of Warsaw, and 63 more — each profile links out to that provider’s APIs, schemas, and governance artifacts.

Related regions by shared providers: Europe, France & Iberia, and United Kingdom & Ireland. Browse every sales region at regions.apis.io.

Region mapping is derived from three explicit signals: a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. It surfaces what is signalled and intentionally infers no further — a provider that says nothing about where it is appears in no region at all. This is a map of stated headquarters, not of markets served. A London company selling across Europe is listed under United Kingdom & Ireland only, and several of the largest API providers carry no geographic statement of any kind, so they appear here nowhere.

About this region

APIs from Central & Eastern Europe — Poland, Czech Republic, Hungary, Romania, Slovakia, the Balkan states, and the post-Soviet space. Strong developer-services concentration and a meaningful share of the open-source API tooling ecosystem.
