VK Captcha
VK Captcha (Not Robot) is VK's interactive captcha that uses checkbox verification and slider puzzle challenges to verify users.
What is VK Captcha?
VK Captcha (also known as 'Not Robot' captcha) is VKontakte's interactive verification system that appears on login pages, registration forms, and when performing rate-limited actions. It comes in two variants: a simple checkbox ('I'm not a robot') and a more complex slider puzzle where a scrambled image must be reassembled by dragging a slider. CaptchaSolv automatically detects the captcha variant and solves both types. The solution returns a success_token JWT that must be included in your form submission.
