🇰🇷Payments & Money Movement in South Korea
6 payments & money movement providers in South Korea, publishing 58 APIs.
Payments & Money Movement in South Korea — 6 providers on the APIs.io network sit in both cohorts, and between them they publish 58 indexed APIs.
All 6 publish at least one machine-readable API — unusual, and worth noting against most cells in this grid.
By Kin Score band: 2 thin, 2 emerging, 1 strong, and 1 developing.
Leading by rating: PortOne, Payple, Toss Payments, Kakao, Toss, and KakaoPay.
Country membership reads a tag, a stated headquarters or a stated nationality. A provider lands in South Korea when one of its own top-level tags names the country, when its own description states a headquarters that names the country or one of its cities, or when it describes itself by nationality (“a French company”; roadmap#542, #719). Region words (“Latin American”), language uses (“French-speaking”) and a city named outside a headquarters statement are not counted, so this cell is a floor, not a census.

Payments & Money Movement elsewhere
This page is the intersection of two independently computed cohorts:
South Korea and
Payments & Money Movement. A provider appears here only when it is
already a member of both. South Korea membership is matched on tag, stated HQ,
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.
