Do you mean to say how do I use this stuff? You can find the documentation [here][1] or there's a Get Started section at the right of this page. For example if you want to see a list of users you could send a web request to http://api.stackoverflow.com/1.0/users and parse then JSON response. Now if you want to find out details about a particular user lets say your details http://stackoverflow.com/users/566610/jared Do you see the number 566610 thats the id. Every question, answer, comment ,or user has a id. So here you need to send your web request to http://api.stackoverflow.com/1.0/users/566610 **Your JSON response :** { "total": 1, "page": 1, "pagesize": 30, "users": [ { "user_id": 566610, "user_type": "registered", "creation_date": 1294388578, "display_name": "Jared", "reputation": 28, "email_hash": "e51f7fdd3c09fc9246278abf89f1881e", "age": 19, "last_access_date": 1294538702, "website_url": "http://wphax.com", "location": "Wisconsin, US", "about_me": "<p>Freelance WordPress Expert</p>\n", "question_count": 2, "answer_count": 2, "view_count": 1, "up_vote_count": 0, "down_vote_count": 0, "association_id": "d0249d62-3c97-4b50-9df1-8c7f377846f6", "user_questions_url": "/users/566610/questions", "user_answers_url": "/users/566610/answers", "user_favorites_url": "/users/566610/favorites", "user_tags_url": "/users/566610/tags", "user_badges_url": "/users/566610/badges", "user_timeline_url": "/users/566610/timeline", "user_mentioned_url": "/users/566610/mentioned", "user_comments_url": "/users/566610/comments", "user_reputation_url": "/users/566610/reputation", "badge_counts": { "gold": 0, "silver": 0, "bronze": 4 } } ] } Take one more example. Lets assume we want to find out list of questions for this you should send your web request to http://api.stackoverflow.com/1.0/questions and if you want questions related to a particular tag for example wordpress your url will be http://api.stackoverflow.com/1.0/questions?tagged=wordpress I hope this helps.
