Investing & Venture Capital in Japan & Korea

15 investing & venture capital providers across Japan & Korea, publishing 44 APIs.

15 providers 44 published APIs 44 indexed documents

Investing & Venture Capital across Japan & Korea — 15 providers on the APIs.io network sit in both cohorts, and between them they publish 44 indexed APIs.

9 of the 15 publish at least one machine-readable API; 6 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: 6 emerging, 5 minimal, 3 developing, and 1 thin.

Leading by rating: JPX (Japan Exchange Group), Dunamu, 한국주식데이터 (aikstockdata), Korbit, Bithumb, Woodstock, 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.

This page is the intersection of two independently computed cohorts: Japan & Korea and Investing & Venture Capital. 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.
