I am thinking of adding gamification to my app Finderous (http://www.findero.us) and want to know if anybody has used any such similar apis for their projects.
It will be easier for me to develop the framework myself, but I want an opinion from someone who has used such apis.
What I need:
1. Users of the app need to spend some credits to post a question on Finderous.
2. Users who reply to questions, earn credits.
3. Users need to buy credits if they run out of credits to post questions.
4. If users want a detailed answer (currently the limit is 222 chars) they have to spend more credits to post such a question.
5. Users who reply to most questions at a certain place become champions of that place and get rewarded with extra credits.
6. Users who want to cash out the credits can do so using real word deals and rewards.
Any suggestions?
