Util::AntiGate - CAPTCHA recognition via the AntiGate service
Scraper overview
This scraper is usually used as a plug-in component in other scrapers where it may be necessary to solve image captchas, for example: 
SE::Yandex, 
Check::RosKomNadzor, as well as custom JavaScript scrapers.
The principle of this scraper is to send a captcha image to a solving service and receive the text value shown on the captcha in response. The accuracy of solving depends only on the solving service and sometimes on the captcha settings.
The process of connecting and configuring this scraper is described in detail in the Anti-captcha settings article.
