With the API Handelsregister Zoeken you can search for a company by, for example, entering the trade name or place.
Looking for more information? Each search result has a hypermedia link to the API Basisprofiel and/or Vestigingsprofiel, also known within REST as HATEAOS. Basisprofiel can only be requested with a Chamber of Commerce number and Vestigingsprofiel only with a location number.
