Frequently asked questions about the Ukraine KYB API
What company data can I verify in Ukraine?
For a Ukraine company, the API returns the company record read live from the Unified State Register of Legal Entities, Individual Entrepreneurs, and Public Organizations: 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 Ukraine availability.
Does the API return beneficial ownership (UBO) data for Ukraine companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Ukraine 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 Unified State Register of Legal Entities, Individual Entrepreneurs, and Public Organizations discloses. See the UBO API.
Can I retrieve official registry documents for Ukraine companies?
Yes. The default document set for Ukraine includes Registry Extract, retrieved by default. List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
