About this API
data.go.kr is South Korea's official public data portal — one of the largest government API catalogs in Asia. It exposes thousands of services from public institutions. Each service requires a free key, granted after registration and approval.
Frequently asked questions
Do I need an API key?
Yes — it requires a free key, granted separately for each service after registration.
What data does this API return?
South Korean Government data and services by service key — from statistics to transport, in JSON or XML.
Can this API be called directly from a browser?
Not easily — key/registration-based authentication requires a server-side call and is not suitable for frontend code visible to visitors (which is why there is no live "Try it" button here).
Who runs this API?
The Government of South Korea (NIA). Documentation: data.go.kr.
