Frequently asked questions about the Curaçao KYB API
What company data can I verify in Curaçao?
For a Curaçao company, the API returns the company record read live from the Curaçao Chamber of Commerce & Industry: the entity name, type, status, registration number, address, and registration date, along with the controlling parties, and the available registry documents. See the table above for the full Curaçao availability.
Does the API return beneficial ownership (UBO) data for Curaçao companies?
For Curaçao, the Curaçao Chamber of Commerce & Industry does not publish shareholder or beneficial-owner data, so the API returns the company record and the controlling parties and officers rather than a shareholder or beneficial-owner list. Where you need ownership for an entity in a jurisdiction that does publish it, the recursive org-chart (GET /v2/Companies/{caseCommonId}/org-chart) resolves it. See the UBO API.
Can I retrieve official registry documents for Curaçao companies?
Yes. The default document set for Curaçao includes Registry Extract, retrieved by default. List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
Is there a free sandbox for testing Curaçao company verification?
Yes. The Know Your Customer sandbox at https://api.knowyourcustomer.dev is a free, high-fidelity test environment. Request free sandbox access to start testing.
