Announcing the PLoS Article-Level Metrics API

We’re pleased to announce that the PLoS Article-Level Metrics API is now available! Since March 2009, we’ve been aggregating metrics for every article with the PLoS Article-Level Metrics application and displaying the data on articles published at PLoS. Now the Article-Level Metrics API is available for the community to retrieve the same data and to create mash-ups with the metrics. If you’ve entered the PLoS/Mendeley Binary Battle, this is also an additional source to use along with the PLoS Search API.

Data that can be retrieved from the PLoS Article-Level Metrics API for every PLoS article include:

• Usage statistics for HTML page views, PDF downloads and XML downloads for each article from the Public Library of Scienceand PubMed Central websites.
• Citation counts from PubMed Central, CrossRef, Scopus.
• Number of times an article has been bookmarked at CiteULike.
• Number of blog posts mentioning an article in Nature Blogs.
