RateItAll offers the only consumer rating API that can also help you promote your site's content.
Here's how it works:
Select API partners are invited to publish their data on RateItAll.com where it will be exposed to RateItAll's 1M monthly visitors.  Each page generated with an API partner's content will contain prominent links back to the partner, as well as full attribution.  
In this way, RateItAll can help drive traffic back to its API partners.

For examples of content published on RateItAll.com using RateItAll's API, please see our directory of CrunchBase Companies or our database of Netflix Movies
