Payments & Money Movement across Japan & Korea — 15 providers on the APIs.io network sit in both cohorts, and between them they publish 20 indexed APIs.
12 of the 15 publish at least one machine-readable API; 3 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: 7 thin, 2 developing, 2 emerging, 2 minimal, 1 exemplar, and 1 strong.
Leading by rating: PAY.JP, PortOne, Payple, Paidy, LayerX, Toss Payments, and 9 more.
Region membership is derived from three explicit signals — a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. This is a map of stated headquarters, not of markets served.

All of Payments & Money Movement →
This page is the intersection of two independently computed cohorts:
Japan & Korea and
Payments & Money Movement. A provider appears here only when it is
already a member of both. Japan & Korea membership is matched on tag, name pattern, 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 region here is available over the APIs.io API and to AI agents over MCP.
