Here at Maxis, we're working on some features to help the community create their own Spore applications. We're collecting these features into a web-based Spore API. Using simple web services, you can access our huge database of creations and creators. Check out the gallery to see apps made with the Spore API. The documentation section has reference sheets and samples to get you started. If you have questions, feedback, or want to announce your awesome app, head over to the forum.
