Is it possible to integrate a cadastral map with a Yandex map?

Question

JavaScript

Hello, we are making a service based on the Yandex map, there is a question of displaying a cadastral map on it, as implemented here , but this service does not share data and does not provide an API, there were similar questions in old questions, but I still did not find an answer, maybe someone I implemented something like this and will tell you where to dig, I will be very grateful for the help!
