=== Query API key information API

++++
<titleabbrev>Query API key information</titleabbrev>
++++

Retrieves information for API keys with <<query-dsl,Query DSL>>
in a <<paginate-search-results,paginated>> fashion.

[[security-api-query-api-key-request]]
==== {api-request-title}

`GET /_security/_query/api_key`

`POST /_security/_query/api_key`

[[security-api-query-api-key-prereqs]]
==== {api-prereq-title}

* To use this API, you must have at least the `manage_own_api_key` or the `read_security`
cluster privileges.
* If you have only the `manage_own_api_key` privilege, this API returns only
the API keys that you own. If you have the `read_security`, `manage_api_key` or greater
privileges (including `manage_security`), this API returns all API keys
regardless of ownership.

[[security-api-query-api-key-desc]]
==== {api-description-title}

Use this API to retrieve the API keys created with the
<<security-api-create-api-key,create API key API>> in a paginated manner.
You can optionally filter the results with a query.

[[security-api-query-api-key-query-params]]
==== {api-path-parms-title}

`with_limited_by`::
(Optional, Boolean) A boolean flag to return the snapshot of the owner user's role descriptors
associated with the API key. An API key's actual permission is the intersection of
its <<api-key-role-descriptors,assigned role descriptors>> and the owner user's role descriptors
(effectively limited by it). An API key cannot retrieve any API key's limited-by role descriptors
(including itself) unless it has `manage_api_key` or higher privileges.

[[security-api-query-api-key-request-body]]
==== {api-request-body-title}

You can specify the following parameters in the request body:

`query`::
(Optional, string) A <<query-dsl,query>> to filter which API keys to return.
The query supports a subset of query types, including
<<query-dsl-match-all-query,`match_all`>>, <<query-dsl-bool-query,`bool`>>,
<<query-dsl-term-query,`term`>>, <<query-dsl-terms-query,`terms`>>, <<query-dsl-ids-query,`ids`>>,
<<query-dsl-prefix-query,`prefix`>>, <<query-dsl-wildcard-query,`wildcard`>>, <<query-dsl-exists-query,`exists`>>,
and <<query-dsl-range-query,`range`>>.
+
You can query the following public values associated with an API key.
+
.Valid values for `query`
[%collapsible%open]
====
`id`::
ID of the API key. Note `id` must be queried with the <<query-dsl-ids-query,`ids`>> query.

`type`::
API keys can be of type `rest`, if created via the <<security-api-create-api-key, Create API key>> or
the <<security-api-grant-api-key, Grant API key>> APIs, or of type `cross_cluster` if created via
the <<security-api-create-cross-cluster-api-key, Create Cross-Cluster API key>> API.

`name`::
Name of the API key.

`creation`::
Creation time of the API key in milliseconds.

`expiration`::
Expiration time of the API key in milliseconds.

`invalidated`::
Indicates whether the API key is invalidated. If `true`, the key is invalidated.
Defaults to `false`.

`invalidation`::
Invalidation time of the API key in milliseconds. This field is only set for invalidated API keys.

`username`::
Username of the API key owner.

`realm`::
Realm name of the API key owner.

`metadata`::
Metadata field associated with the API key, such as `metadata.my_field`. Because
metadata is stored as a <<flattened,flattened>> field type, all fields act like
`keyword` fields when querying and sorting.

NOTE: You cannot query the role descriptors of an API key.

+
By default, you cannot page through more than 10,000 hits using the `from` and
`size` parameters. To page through more hits, use the
<<search-after,`search_after`>> parameter.

`size`::
(Optional, integer) The number of hits to return. Must not be negative and defaults to `10`.
+
By default, you cannot page through more than 10,000 hits using the `from` and
`size` parameters. To page through more hits, use the
<<search-after,`search_after`>> parameter.

`sort`::
(Optional, object) <<sort-search-results,Sort definition>>. Other than `id`,
all public fields of an API key are eligible for sorting. In addition, sort can
also be applied to the `_doc` field to sort by index order.

`search_after`::
(Optional, array) <<search-after,Search after>> definition.


[[security-api-query-api-key-response-body]]
==== {api-response-body-title}

This API returns the following top level fields:

`total`::
The total number of API keys found.

`count`::
The number of API keys returned in the response.

`api_keys`::
A list of API key information.

[[security-api-query-api-key-example]]
==== {api-examples-title}

The following request lists all API keys, assuming you have the
`manage_api_key` privilege:

A successful call returns a JSON structure that contains the information
retrieved from one or more API keys:

effective permissions are an intersection of its assigned privileges and the point-in-time snapshot of
the owner user's permissions.

<1> The owner user's permissions associated with the API key.
It is a point-in-time snapshot captured at <<security-api-create-api-key,creation>> and
subsequent <<security-api-update-api-key,updates>>. An API key's
effective permissions are an intersection of its assigned privileges and
the owner user's permissions.

You can also retrieve the API key by name:
