Where is paid access to constantly updated data on the boundaries of administrative districts of cities and regions through api?

Question

Google Maps

I can’t find a single normal service, for example, you’ll score Northern Tushino, Moscow, so that the coordinates of the borders are displayed, I need this for a real estate site for 4 days I’m suffering, it’s just a scribe.

At least do everything yourself, maybe someone knows how to pull out the data on the borders of the districts from Yandex or Gul, otherwise https://www.openstreetmap.org is buggy nonsense?

I created a topic here, unfortunately they can't help here https://forum.openstreetmap.org/viewtopic.php?pid=...

Answer 1

You can not legally pull the boundaries of Google and Yandex.
On the forum, they gave a link to sets from nexgis, this is quite enough for such tasks.

Answer 2

I wrote such a script, I drove it in a circle, because a list of the wrong borders used to be drawn there, it seems that I
pulled out all the clean data.
The bottom line is, first we filter by boundary=administrative, then in the resulting garbage we look for type administrativ and in display_name in the first value the district, also the word district in the query should be in the results on the left or right side of the district name, we also check this.
