Debugging and Logging

I added Laravel debugging and logging, since I can't get a valid result (and why shouldn't I contribute when I already wrote it)...

I always get a 400 (Bad Request) error - double checked the search engine id and daily request (which are still 0)... 
I really don't know what is going wrong (or what I am doing wrong)...



p.s.: Is "illuminate/support" really required? - I had to require it in my projects composer file, otherwise it wouldn't work.
