An API for the IEDB-AR has been available since Release 2.5 and includes a RESTful interface to the MHC class I and II prediction tools, the processing tool, MHC-NP, and B cell epitope prediction tools. This allows users at other sites to perform predictions on the server in batch mode without having to install any software on their own systems. Additionally, users will always be assured that they are using the latest version of the tools. A full description of the API can be found here: Tools-API
