The Kyckr API connects you to a live network of 300+ company registries across 100+ countries — delivering structured company data and original register documents in real time, directly from official sources. One integration. No registry contracts. No fragmented connections to maintain.

​
What you can retrieve

  • Structured company data (JSON/XML, normalised)
  • Director, officer, and shareholder information
  • Original documents from company registers (PDF)
  • Official filing records

​
Why Kyckr

Every company registry has its own authentication model, technical interface, access restrictions, and data format. Building direct connections is expensive to establish and operationally demanding to maintain — and scaling them internationally is a significant engineering commitment. Kyckr provides a single API layer that abstracts this complexity entirely. Instead of managing multiple registry integrations, you connect once and access a global registry network that has been built and maintained for over 20 years.

​
What makes Kyckr different

Direct registry sourcing

All data is retrieved from official company registers — in real time or near real time at the point of request. No third-party aggregation, no stale data passed off as live.

Structured data and source documents

The API returns machine-readable company data in a normalised structure (JSON/XML) alongside original register documents (PDF) — supporting both automated workflows and documentary audit trails.

Global coverage, one integration

A single API connection gives you access to 300+ company registries across 100+ countries — built and maintained by Kyckr over more than 20 years.

​
Use cases

Know Your Business (KYB) Kyckr is commonly integrated into KYB workflows to support company identification, verification of registration details, confirmation of directors and shareholders, and retrieval of official register documents. It is used within proprietary onboarding systems, third-party KYC orchestration platforms, and customer lifecycle management (CLM) systems. Entity verification during onboarding Kyckr is also used as a first-line compliance check at the point of onboarding. A typical workflow queries the search endpoint to locate an entity, then the lite profile endpoint to retrieve registered details — comparing returned data against customer-supplied information programmatically, and flagging or rejecting the application if there is a mismatch.

​
How a typical integration works

Kyckr is designed to support the full KYB journey — from initial company identification through to document retrieval and ownership verification.
1

Search for a company

Query by company name or registration number. The API returns a list of matched entities from the relevant company registry.
2

Retrieve a company profile

Once a company is identified, retrieve a profile. Two levels are available:
  • Lite profile — core company details for fast onboarding checks and pre-fill. Live data, sourced directly from the company register at the point of request.
  • Enhanced profile — full structured data including directors, officers, and shareholders (where registered), also sourced live from the company register.
3

Unwrap the ownership structure (if required)

If entities appear above your ownership threshold, Kyckr’s UBO Verify capability can unwrap the corporate structure and auto-calculate ultimate beneficial owners (UBOs). If all UBOs are identified from the initial profile, this step is not required.
4

Retrieve original documents (if required)

For registries where structured data is limited, or where documentary evidence is required, original extract PDFs can be ordered directly from the company register. Additional document types — annual accounts, articles of association, change notifications — are also available.
Data availability and response times vary by jurisdiction. Some registries return data in real time; others operate on a request-and-retrieve basis. See the Country Coverage guide for details.
