The XSEDE Information Services warehouse contains information about infrastructure, projects, and people. The information is aggregated from various information sources, cross-referenced, and made available thru web APIs. These web APIs are grouped by target user audience and by the type of information they contain:

  • Discovery APIs: the most useful APIs for developers/users which integrating information from all available sources
  • Specific Source APIs: provide access to information from a single source
  • Client Tool APIs: provide access to the combination of information needed by specific client tools

Each of these API groups are described in more detail below. All these APIs return information in JSON format. Some also return information in XML, CSV, and HTML formats. The following (Swagger) self documentation describes each API's URLs and arguments:
