In order to use open data API or XML services, it is necessary to sign an agreement with the Registers and Information Systems Center.

Initially, the existing API (XML) services of the Business Register have been made available for the use of open data, which are planned to be updated by the RIK soon.

We would appreciate it if you could take a moment to share your suggestions and feedback with us about the Open Data API.

Concluding the contract:

To conclude the contract, please enter the e-Business Register portal and fill out the contract application (Read also: General conditions for the use of inquiry systems)
Contract applications are reviewed within five working days, after which the necessary information is sent to the administrator user
When concluding the contract only for the use of the e-Business Register API services, the use of the services is free of charge

Requirements for the API Services:
