  Welcome to the our version 1 API documentation. All comments can be written in (support [Markdown](http://daringfireball.net/projects/markdown/syntax) syntax)
  
  We only guarantee updated metrics for items with an ImpactStory-supplied api key. 
  To request an ImpactStory-supplied api key, send an email to team@impactstory.org
  
  The examples below are for getting metrics for a [BMC Research Notes paper](http://www.biomedcentral.com/1756-0500/4/487) using its [PubMed ID 22075173](http://www.ncbi.nlm.nih.gov/pubmed/22075173). 
  Alternatively, it could be queried by its DOI (10.1186/1756-0500-4-487) by replacing the namespace and identifier in the examples below.  For example, /v1/item/pmid/22075173?key=YOURKEY returns the same values as /v1/item/doi/10.1186/1756-0500-4-487?key=YOURKEY
