jotun

A Clojure library designed to interact with Anti-Captcha services online. The idea is to have an unique interface to deal with providers of anti-captcha utilities.

The first to be implemented will be the Anti-Captcha from Coliseo. I've being using this service for some time and I was missing a library to provide interface for them and other facilities.

jotun are Nordic mythological creates with great-strength that are often against the gods. The role and characteristics of the giants are often unclear and contradictory, from brutal beasts with childish intellect to wise ancient creatures. Peak your side.

Tasks implemented/available:

• ImageToText: solve usual image captcha
• NoCaptcha: Google Recaptcha puzzle solving
• FunCaptcha: rotating captcha funcaptcha.com
• SquareNetText: select objects on image with an overlay grid
• GeeTest: sliding captcha from geetest.com
• CustomCaptcha: image captcha with custom form.

There are still many decisions related to public interfaces and project structure to be developed.

Critical

The Anti-Captcha service is paid, therefore you need to get an account at their WebSite and charge it with a few dolars. It's the cheapest solution I found in the market.

Please provide you client key as a environment variable called apikey. The package will manage to get the correct result and use it accordingly.
