91 providers 234 APIs

South Korea on the APIs.io network surfaces 91 providers that carry a South Korea tag — together publishing 234 indexed APIs.

Notable providers include PortOne, Actionpower, TheCarApi, Ab180, Seoul National University, 한국주식데이터 (aikstockdata), and 85 more — each profile links out to that provider’s APIs, schemas, and governance artifacts.

Related countries by shared providers: China. 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.
