General

You request an API subscription and receive an API key. This key allows you to retrieve information about companies, such as their name, address, or KVK-number. 

With the "KVK Handelsregister Zoeken" API, you can search for a company by entering its trade name or location, for example. Each search result provides a link that allows you to request more information via other APIs. 

Want to know more? Check the API documentation.

This can be done in two ways (both free of charge): 

1. Via our SwaggerUI with associated test data.
2. Via your own software with our test API key: l7xx1f2691f2520d487b902f4e0b57a0b197. Check the API documentation for more information.
