API Document for Yahoo Services.

Hi YDN members,
I am new to  this forum, I have few requests to ask the community.

I am developing an yahoo service application with News, Finance, Movies and Cricket on a Mobile platform. (I need API's for these services like the one Flickr provides, with result/return format being anything. It can be JSON, XML, RSS, atom etc..)

I already have an Flickr application. I found the Flickr API service easily when I started to develop it. But for the above services I don't know where to find all the API's available for the above mentioned services. Please Guide me where I can found the complete list of API.

I have gone through YQL, But I felt like a stranger there. My back ground is C/C++/core Java. I need Plain REST API's for all the above services or please guide me how to build the API from the YQL.


Thanks
RamaKrishna.
