Util::AntiGate - captcha recognition via the AntiGate service
Scraper overview
This scraper is typically used as a plug-in component in other scrapers where image captcha solving may be required, for example: 
SE::Yandex, 
Check::RosKomNadzor, as well as in 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 the solving depends solely on the solving service and sometimes on the captcha settings.
The process of connecting and configuring this scraper is described in detail in the article Anti-captcha settings
