Antigate is an real-time CAPTCHA to text decoding service that utilizes human workers from around the world. The Antigate API allows users to upload CAPTCHAs, set parameters, receive the decoded CAPTCHA value, retrieve the status of the CAPTCHA as well as several account related functions an queries. The service cost starts at .7USD per 1000 images depending on volume, and comes with an average decoding speed of 15 seconds. The API uses REST calls and can return XML.
The Death By CAPTCHA API is one of three CAPTCHA beating APIs posted to our index in just the last week. After taking a look at them I can say that they are just as seedy and sketchy as you would imagine. Even so, I don't see these services going away anytime soon. The existence of super cheap CAPTCHA beating systems begs the question, how effective is the visual CAPTCHA today?
