Central & Eastern Europe on the APIs.io network surfaces 20 providers mapped to this sales region — together publishing 28 indexed APIs.
Notable providers include Kontomatik, University of Warsaw, Charles University, OPSI Slovenia, Official Ukrainian Government Portal, data.zagreb.hr Official Open Data Portal, and 14 more — each profile links out to that provider’s APIs, capabilities, schemas, and governance artifacts.
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.
