You can request HIP tests from the url link:

http://smartcha.net/main/request.jsp



When you request a HIP test, an XML response will be returned, e.g.:
<smartcha>
<question>what do you use to brush your teeth?</question>
<answer>6a45fcc6cf26abbd6a4b1730558f66e1</answer>
</smartcha>


There will be two elements of the XML response question and answer.
Question element is the pure-text HIP test to be solved by users.
Answer element is the MD5 hash of the lower case answer.
