We offer our customers statistical data to different themes in different data sets. Following the open data approach we want wo offer an OData API or REST API according to Statistic Netherlands open data portal: https://opendata.cbs.nl/statline/portal.html?_la=en&_catalog=CBS

https://opendata.cbs.nl/ODataApi/odata/37325eng

With this simple URL customers can integrate it into e.g. Excel and gain direct access on the base data set behind to creat own pivot tables on professional level.

Probably adequate way would s.th. like offering a REST Get-Method as JSON to an data set.
