Hey I am sure this question has been asked 10000 times before and I am pretty sure the answer is no based on the fact I have not seen any information in the documentation on it. But I thought it would be cool to make a giant bomb android app that had all the information on your xbox and steam achievements and I was wondering if I could get this information using the api?
User information is not aviliable via the API. All you can pull from is the RSS feeds, such as http://www.giantbomb.com/feeds/activity/Freek/
Also if I remember correctly they cannot re-release the Achievement information through an API due to the deal they have with Microsoft.
