Answer 2

As far as I know, Yandex and Google updates are something virtual, and they get them using the issuance parsing.
To be more precise, they parse the results on the same queries, and when the results in the search have changed, this is considered the update date.
So you can get dates only from the services themselves that monitor this in light mode, or, as described above, parse the output itself and monitor changes in some signs (positions , number of results, etc.).
There is no official source for these dates.
