Danish property listing portal — no public API, browser automation only.
VisitDenmark operates the GuideDanmark API, a live, OAuth2-gated (password grant) database of roughly 30,000 tourism products — attractions, activities, and events — in Danish, English, and German, returned as JSON or XML.
OAuth2 password-grant auth confirmed live (an unauthenticated call to a protected endpoint returns 401, not a dead link). Owned and operated directly by VisitDenmark.
