The Estonian e-Business Register (e-Äriregister) is the official commercial register of Estonia, operated by the Centre of Registers and Information Systems (Registrite ja Infosüsteemide Keskus, RIK). It publishes company, related-person, beneficial-owner, annual-report and pledge data as open data through a REST API (ar-rest.rik.ee, API-key/bearer token), sixteen X-Road style SOAP/XML services (ariregxmlv6.rik.ee, WSDL published, test environment demo-ariregxmlv6.rik.ee) and daily open data downloads in JSON, XML and CSV. Use requires a free contract with RIK, except the autocomplete and e-invoice recipient services.
