API - Pass a point to server return data

Newbie question.


What I want to do is given an x, y coordinate, I want to pass it to a Census server and have it return data for the block group it intersects. This is an example of what I would like:*&f=pjson


I have tried doing (which does not return any features):*&returnGeometry=true&returnIdsOnly=false&returnCountOnly=false&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&f=pjson


Does TigerWeb require an API key, and if so, what is the format for inserting it into the http string?


Later, I would like to pass the server a polygon and have it return the summation of say population within the block groups that intersect the given polygon.
