Data Retrieval

Looking to input a list of domains and then get back a csv file with additional columns. The information I am looking to extract is page rank, # of backlinks, indexed on google (Y/N), dmoz (Y/N) I don't care how you check but you want to make sure you either use an API to extract the information. If you are going to be checking google by making calls to google, you will need to make sure you don't run all 500 domains at once. I will be entering about 500 domains at one time. If you make 500 calls to google within the same few seconds, you will get banned.
