About Open Government, Netherlands

The API provides access to metadata for all datasets published on data.overheid.nl, the Dutch open government data portal. It is built on CKAN and accessed via https://data.overheid.nl/data/api/3/, following the CKAN API structure documented on the CKAN website; the CKAN API v3 is not a REST API and no complete OpenAPI spec exists for it yet. All information retrievable through the API is licensed under CC-0, permitting reuse.

Beyond dataset metadata, a separate set of APIs allows access to data requests, applications, groups, organizations, and communities associated with data.overheid.nl, with further documentation provided in Dutch on a separate documentation server.

This API is intended for developers building applications or tools that need programmatic access to Dutch government open data listings and related organizational information.
