### Business Register Checks The **Business Register Checks** APIs allow you to search and retrieve company information from official and commercial business registers. These endpoints help verify legal entities, support KYB (Know Your Business) processes, and ensure compliance with AML and onboarding requirements. ZignSec provides multiple lookup options depending on the depth of data required: - **Search Company** – Find companies by name, organization number, or partial identifiers. - **Lookup Company (Basic)** – Retrieve essential registration details, such as company name, ID, and status. - **Lookup Company (Advanced)** – Access extended company data, including ownership, address, financial, and registry information. Use these APIs to automate company verification and enrich onboarding workflows with authoritative business data.
