Images and associated data may be requested from the National Library of Medicine (NLM) Computational Photography Project for Pill Identification (C3PI) extra-mural development server by using an integrated RESTful web applications programing interface (API) service (Costello, 2012) (Fielding R. T., 2000). Requests are made using the HTTP GET method (Robin Berjon, 2012), with results being returned in either JavaScript Object Notation (JSON) (Crockford, 2006) or Extensible Markup Language (XML) (W3C, 2007) encoding. More complex requests such as image validation can be made using a POST (Robin Berjon, 2012) request. Database modification via PUT and DELETE http methods is prohibited (Robin Berjon, 2012).
