I have experience using APIs like this, as well as text formatting and parsing.
To do this, I would create an application which made the API requests and formatted them appropriately. I can do this application in a wide number of technologies, including Node.js, Java, C#, or with a web interface if you prefer. additional features can be added as well.
Design details include the interface with which you enter the product reviews, the format which the application produces (perhaps you would also like the data in XML or JSON format), and the way in which the data is accessed (do you want to put multiple URLs in or just one?)
