When you are using a web application API such as Yahoo, you need an "Application ID" to authenticate your application before Yahoo provides you the data. The good thing about the inbound links API is that it is FREE; you will not need to pay to gather useful data from Yahoo.

It is also important that your use of the Yahoo Site Explorer API will not violate the usage policy.
