I would like to find out if I can use the cian.ru site API. The information is not written publicly about the API, but I could find an example of using it on one of Cyan's services. Here is an example link

I need this to automatically add apartments to the database of my site by loading lists from this very API.

Does this not contradict any licenses?

    Why don't you ask the site developers? If they do, all is well. If not, don't do that. - VladD

If there are no public documents on the API, then you, of course, can use it, but the problem is that the developers can change it at any time and your project will break.

Moreover - the license agreement CIAN.RU is here . As I understand it, the use of their API falls under the clause:

7.2.3. use automated scripts (programs) to collect information on the Sites and / or interact with the Sites and their functionality without special permission from the Site Administration;

Therefore, if the data from there is really needed for a serious project on a systematic basis - I recommend contacting the developers.
