3D FlipBook - I have a software that creates books. Question about your licensing

Our software is a Saas product that creates books. I would like to allow users to view their book (pre-purchase) by displaying it on a web page and using your jquery plugin to display their book on our site. Is there a license that I can buy that allows me to use your plugin to display our user's books on our website? If so, what's link to buy the license? Thank you.
