Blockchain, Crypto & Web3 in Japan & Korea

12 blockchain, crypto & web3 providers across Japan & Korea, publishing 48 APIs.

12 providers 48 published APIs 48 indexed documents

Blockchain, Crypto & Web3 across Japan & Korea — 12 providers on the APIs.io network sit in both cohorts, and between them they publish 48 indexed APIs.

8 of the 12 publish at least one machine-readable API; 4 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 emerging, 3 thin, 3 minimal, 1 exemplar, and 1 strong.

Leading by rating: PAY.JP, Dunamu, Korbit, Dsrv, Bithumb, bitbank, and 6 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 Blockchain, Crypto & Web3. 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.
