About this API
data.gov.hk is the official open-data portal of the Hong Kong Government, built on CKAN. It exposes datasets from public institutions through a uniform REST API — statistics, transport, environment, the economy.
Frequently asked questions
Do I need an API key?
No, the API is public and free — no registration, no key required.
What data does this API return?
Metadata and contents of Hong Kong Government datasets (CKAN) — title, description, organisation and resources.
Can this API be called directly from a browser?
Not directly — this endpoint does not return a CORS header (or requires specific query parameters), so it is called server-side (which is why there is no live "Try it" button here).
Who runs this API?
The Government of Hong Kong (OGCIO). Documentation: data.gov.hk.
