Frequently asked questions about the Slovakia KYB API
What company data can I verify in Slovakia?
For a Slovakia company, the API returns the company record read live from the Business Register of the Slovak Republic: the entity name, type, status, registration number, address, and registration date, along with the controlling parties, the shareholders and beneficial owners, and the available registry documents. See the table above for the full Slovakia availability.
Does the API return beneficial ownership (UBO) data for Slovakia companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Slovakia companies and exposes them as a recursive ownership org-chart (GET /v2/Companies/{caseCommonId}/org-chart), tracing control through holding companies to the individual beneficial owners. The depth available depends on what the Business Register of the Slovak Republic discloses. See the UBO API.
Can I retrieve official registry documents for Slovakia companies?
Yes. The default document set for Slovakia includes Registry Extract, retrieved by default, with additional documents available on demand (Full Registry Extract). List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
