Our Mission
Korean business verification APIs have long been complex, expensive, and poorly documented. Teams waste weeks on integration and pay steep per-lookup fees.
We built Kynode as a simple, affordable, well-documented alternative. Our developer-first approach includes English and Korean support, clear error messages, and predictable REST semantics.
We source authoritative data from Korea’s National Tax Service so you can trust the numbers behind every verification.
