[[info-api]]
== Info API

The info API provides general information on the installed {xpack}. This
information includes:

* Build Information - including the build number and timestamp.
* License Information - basic information about the currently installed license.
* Features Information - The features that are currently enabled and available
  under the current license.

The following example queries the info API:

[source,js]
------------------------------------------------------------
GET /_xpack
------------------------------------------------------------
// CONSOLE

Example response:
[source,js]
------------------------------------------------------------

// So much s/// but at least we test that the layout is close to matching....

You can also control what information is returned using the `categories` and
`human` parameters.

The following example only returns the build and features information:

[source,js]
------------------------------------------------------------
GET /_xpack?categories=build,features
------------------------------------------------------------
// CONSOLE

The following example removes the descriptions from the response:

[source,js]
------------------------------------------------------------
GET /_xpack?human=false
------------------------------------------------------------
// CONSOLE
