About this API
CVR is Denmark's central register of all companies and entities (equivalent of the KRS/REGON). Data is distributed system-to-system via the Virk portal (Danish Business Authority). Access is free but requires system registration — once granted, you can fetch data by CVR number.
Frequently asked questions
Do I need an API key?
Yes — it requires free system-access registration (granted by the Danish Business Authority).
What data does this API return?
A Danish company's data by CVR number — name, legal form, address, industry and status.
Can this API be called directly from a browser?
Not easily — key/registration-based authentication requires a server-side call and is not suitable for frontend code visible to visitors (which is why there is no live "Try it" button here).
Who runs this API?
The Danish Business Authority (Erhvervsstyrelsen), Virk portal. Documentation: datacvr.virk.dk.
