What is the best way to write a bot for vk?

Question

Python

I want to make a bot that would give information about the group. Those. the user writes a link to the group, and I give out something like this:

Пост, в котором максимальное кол-во лайков: xxxxxxx
Пост, в котром максимальное кол-во репостов: xxxxxx
Пост, в которм максимальное кол-во комментариев: xxx

I learned how to get this information and recognize the group, but several problems arise:
1) If there are a lot of people, then I will have to enter captcha, which is inconvenient for the user (even if I use execute, I will only get 2500 records)
2) If I get information about group more than timeout time, then "rudder collapse" (CALLBACK API using ). (here you can use async)
1) Got a link
2) ?????
n+1) PROFIT
What to do in steps [2,n]? And how to solve the problems that I described above? There was an idea to line up. How are you?

Answer 1

If there are a lot of people, then I will have to enter a captcha, which is inconvenient for the user (even if I use execute, I will only get 2500 entries)

communities do not have captcha, they only have a limit on the number of requests - 20 per second, respectively, in theory you can get up to 20 * 25 * 100 = 50000 records per second,
but there is a quantitative limit on calling the wall.get method , there is nothing can't be helped

Answer 2

Anticaptcha and proxies for money are everywhere
Well, make another request
