Well I have asked them about the API. Also that is open to use. Instead of a user that manually opens some files, copy the names and other information from his dataset and the paste them on that website, I want to write a java code to automatically fills the form and the get the result. So why isn't that ethical?!
I know java and jscript are not the same. I meant that my code uses java to extract the information needed and paste them on that website.
