🇰🇷Financial Technology in South Korea
10 financial technology providers in South Korea, publishing 12 APIs.
Financial Technology in South Korea — 10 providers on the APIs.io network sit in both cohorts, and between them they publish 12 indexed APIs.
5 of the 10 publish at least one machine-readable API; 5 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.
By Kin Score band: 4 minimal, 2 thin, 2 emerging, 1 strong, and 1 developing.
Leading by rating: PortOne, Payple, Toss Payments, Dunamu, Toss, KakaoBank, and 4 more.
Country membership is exact-tag only. A provider lands in South Korea when one of its own top-level tags names the country — there is no headquarters signal on the country axis, unlike the region axis which reads tag, provider-name pattern, and stated HQ. So this cell is a floor, not a census, and it understates by construction — a financial technology company headquartered in South Korea that never tags itself is counted nowhere on this axis. The region cuts read the wider signal set and will generally hold more.

Financial Technology elsewhere
This page is the intersection of two independently computed cohorts:
South Korea and
Financial Technology. A provider appears here only when it is
already a member of both. South Korea membership is matched on tag,
so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
Work with this as data
Every country here is available over the APIs.io API and to AI agents over MCP. Countries is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
