Welcome to the Lasso documentation

These pages give you everything you need to integrate with and use Lasso and its services.

Lasso provides an extensive API that delivers data from multiple sources in simple, consistent formats — company data, ownership, financials, people, and much more. On top of that, Lasso connects directly to your own systems, both standard CRMs and custom setups. This documentation shows you how to do all of it.

These pages describe specific endpoints for some of the modules available to you through the API. With a few exceptions, it's possible to access the data of any module in our portal using the API, but only the endpoints documented in these pages should be considered available without consulting us, as otherwise the endpoints may change without warning. Should you have a specific module you wish be made available, you can send in your request at feedback@lassox.com.

If you have any questions, please don't hesitate to contact us by e-mail or by phone at +45 71 74 78 12.
