  "description": "This operation queries for available free slots with optional parameters, such as date/time range, and specialty.  The server determines which open slots to expose to the application for use in creating new appointments. If neither a start or end date is given then the maximum period as defined by local business rules and starting from when the operation was transacted will be used. \\n\\n Note that all input parameters are simple types allowing either the 'GET'  or the 'POST' syntax to be used to initiate the interaction.  Examples of both are shown below.",
