The Dutch company register at kvk.nl doesn't have an API.

Where can I find open company data for the Netherlands? Ideally with an API.

openkvk is a project to provide Dutch company data. The project has been running since 2009 and there's a mature API.


The OpenCorporates project at https://opencorporates.com/ has more than 2.5 million entries for companies registered in the Netherlands as well: https://opencorporates.com/companies/nl

APIs and developer information for the project can be found at http://api.opencorporates.com/
