Frequently asked questions about the Cayman Islands KYB API
What company data can I verify in Cayman Islands?
For a Cayman Islands company, the API returns the company record read live from the CIG E-services: the entity name, type, status, registration number, address, and registration date, along with the available registry documents. See the table above for the full Cayman Islands availability.
Does the API return beneficial ownership (UBO) data for Cayman Islands companies?
For Cayman Islands, the CIG E-services 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 Cayman Islands companies?
Yes. The default document set for Cayman Islands includes Company Identity, retrieved by default, with additional documents available on demand (Director Details, Detailed Search). List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).

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.
