Regardless of which modules are installed, the following web services are always available:

serverinfo: provides meta data about INTGeoServer itself. This meta data includes the version number as well as capabilities that the server might support

filemetadata: provides various information about a specified file, such as file size and last modified date

advancedfileslist: provides directory capabilities, typically listing all files in a specified directory along with their meta-data

fastfileslist: same as advancedfileslist, except that no meta data provided. Requires the installation of an optional library to work

datatypes: provides the list of data types that are supported. If only the seismic and well modules were installed, this list will list "seismic" and "well"

Each one of these services used the JSON format, both for requests and responses. By default, all web services are stateless.

The URL parameters can be specified either as classic URL parameters (myservice?myparameter=myvalue) or a JSON object (myservice?json={"myparameter"="myvalue"))
