Photo Captcha REST API - SDKs

PhotoCaptcha is an image based captcha used to prevent bots from posting to a website. It presents users with images as opposed to letters that can often be difficult to read. Users are asked to click a series of images from those presented instead of having to type letters. PhotoCaptcha is translated to English, Polish and Italian. PhotoCaptcha is implemented via JavaScript. In order to verify if captcha was solved correctly a user's script needs to contact the API sending PhotoCaptchaResponse and client's IP address. The API uses RESTful calls and responses are formatted in CSV.
