Login to VK through a proxy. How to check the proxy for validity?

Question

PHP

There are several hundred accounts in VK. There is a script that logs in to VK and logs in to a third-party site via oauth. The problem is that each account needs its own IP. For this, a proxy is used. But in VK almost always a non-entered captcha pops up. Is it possible to somehow quickly check the proxy for the ability to log into VK using it?
