How to retrieve youtube videos with a dev key and or dev tag?

I'm working with the Youtube Data API and I'm trying to retrieve a json feed of videos uploaded with a specific Developer API Key or more preferably with a Developer Tag that is assigned to the videos on upload.

I read the API docs and it said to use this URI: http://gdata.youtube.com/fe开发者_开发百科eds/api/videos?key=dev_key_here&v=2&alt=jsonc

That URL gets 100k videos that aren't mine. I should only be getting one video that was uploaded with that my dev key. Any ideas?

I'm going to using ajax to retrieve this dataset.

If you read the API documentation it says that the key is solely used for authentication/identification. If you want to find videos by a user (also your own) then you can use the author parameter for specifying that.

The API documentation for this is here
