Understanding the usage of your publications used to be easy: if it's a book, count the sales. A magazine? Count the subscriptions. An article--count the circulation of the hosting publication. If you're a librarian, just look at how many times it was checked out. For impact, count citations. The digital universe requires new tools to measure these and the Scholarly IQ API is Scholarly's app for putting them right into your application. Scholarly IQ uses SUSHI to harvest COUNTER usage statistics.

Rejoiner is a company that helps online retailers capture, analyze and recover abandoned shopping carts. The company accomplishes this with their Rejoiner API.
