As far as Copyscape pricing is concerned, there are three plans that they offer. The Copyscape Premium search costs 3c for the first 200 words and then 1c for each additional 100 words. Copyscape credits need to be bought in advance. You can purchase them easily through either a credit card or PayPal.

Copyscape also offers a free of cost model by which you can check for plagiarism and detect the stolen content but it is not as powerful as the Premium plan and it does not allow batch search or checking offline content.
