Question

In contact with

Created an interface for searching and downloading audio from VK. For access I use my access_token .
Why, with a large number of requests, it stops producing results (rather, it requires a captcha).
What can be done about it?
Change tokens every time or what?
Or is there another solution?

The response from the VK API will never give a captcha, but it can return data or an error . Response dump will help you.

Hello. Please tell me what VK API returns
