Government — entry 063 of 90
Open Government, Netherlands
Data.overheid.nl is the Dutch national open-data catalogue, running CKAN under the `/data` path (`data.overheid.nl/data/api/3/action/...`). Dataset search and metadata calls work with no key and return JSON. The live API does not send an `Access-Control-Allow-Origin` header, so it must be called server-side or through a proxy rather than directly from browser JavaScript on another origin.
AuthenticationNone requiredCall it straight away — no key, no signup.
HTTPSSupportedTraffic is encrypted in transit.
CORSDisabledBrowser calls need a server-side proxy.
PricingFreeNo paid tier — free for the documented use case.
