One of the goals of Open Access is to allow people to mix and remix information into new and informative mediums. PLOS has a few APIs that make it easy to accomplish exactly this, one of which was recently featured as API of the Week over at ProgrammableWeb, a directory of APIs and interesting mashups. They had this to say about our Article Level Metrics API:
“The new Public Library of Science (PLOS) API provides developers with unusually rich access to their collection’s usage metrics. The API delivers metadata from a varied assortment of outside sources, including social networks, scientific journals, and article databases. This is the kind of API that is as applicable to research applications as it is to social ones.”
Here at PLOS, we use both APIs to power many aspects of our journal websites—search, most viewed articles on homepages, ALMs in search results, the Metrics tab on articles, ALM signposts, and more!—as well as new, stand-alone tools like ALM Reports. 
We’ve previously sponsored contests to build the best apps that use the PLOS APIs and we’re always curious to see what you might build with PLOS data. Want to create a tree diagram of article dissemination through social networks over time? Sounds good! Bump charts of the top 100 cited articles in each journal? Go for it. What about creating a two-dimensional representation of a Julia set with each pixel representing an article all sorted cross-dimensionally through a Mersenne sieve? A bit over our heads, but it’s your vision, after all.
