All available APIs are in the Nokia Qt SDK. If an API is not there [yet] it is because it is in a private beta stage and access to the API is limited and controlled. At times the preparation of the API is done in a rather public way (so you can still see the docs and examples) but the API will only be released for general use once ready, and when done so it will be advertised.
If you have any questions about such projects, please post them in their own Discussions area, e.g. at https://projects.developer.nokia.com/iap/discussion
