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.

`with_profile_uid`::
(Optional, boolean) Determines whether to also retrieve the <<user-profile,user profile>> `uid`, for the API key owner user.
If it exists, the profile uid is returned under the `profile_uid` response field for each API key.
Defaults to `false`.

`typed_keys`::
(Optional, Boolean) If `true`, aggregation names are prefixed by their respective types in the response.
Defaults to `false`.

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

You can specify the following parameters in the request body:

`query`::
(Optional, object) A <<query-dsl,query>> to filter which API keys to return.
If the query parameter is missing, it is equivalent to a `match_all` query.
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-match-query,`match`>>, <<query-dsl-ids-query,`ids`>>,
<<query-dsl-prefix-query,`prefix`>>, <<query-dsl-wildcard-query,`wildcard`>>,
<<query-dsl-exists-query,`exists`>>, <<query-dsl-range-query,`range`>>,
and <<query-dsl-simple-query-string-query,`simple query string`>>.
+
You can query the following public values associated with an API key.
+
NOTE: The queryable string values associated with API keys are internally mapped as <<keyword,`keywords`>>.
Consequently, if no <<analysis-analyzers,`analyzer`>> parameter is specified for a
<<query-dsl-match-query,`match`>> query, then the provided match query string is interpreted as
a single keyword value. Such a <<query-dsl-match-query,`match`>> query is hence equivalent to a
<<query-dsl-term-query,`term`>> query.
+
.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. This is `null` if the key was not configured to expire.

`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`.
Metadata is internally indexed as a <<flattened,flattened>> field type.
This means that all fields act like `keyword` fields when querying and sorting.
It's not possible to refer to a subset of metadata fields using wildcard
patterns, e.g. `metadata.field*`, even for query types that support field
name patterns. Lastly, all the metadata fields can be searched together when
simply mentioning `metadata` (not followed by any dot and sub-field name).

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

`aggs` or `aggregations`::
(Optional, object) Any <<search-aggregations,aggregations>> to run over the corpus of returned API keys.
Aggregations and queries work together. Aggregations are computed only on the API keys that match the query.
This supports only a subset of aggregation types, namely: <<search-aggregations-bucket-terms-aggregation,terms>>,
<<search-aggregations-bucket-range-aggregation,range>>, <<search-aggregations-bucket-daterange-aggregation,date range>>,
<<search-aggregations-bucket-missing-aggregation,missing>>, <<search-aggregations-metrics-cardinality-aggregation,cardinality>>,
<<search-aggregations-metrics-valuecount-aggregation,value count>>, <<search-aggregations-bucket-composite-aggregation,composite>>,
<<search-aggregations-bucket-filter-aggregation,filter>>, and <<search-aggregations-bucket-filters-aggregation,filters>>.
Additionally, aggregations only run over the same subset of fields that `query` works with.

include::{es-ref-dir}/rest-api/common-parms.asciidoc[tag=from]
+
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`.
The `size` parameter can be set to `0`, in which case no API key matches are returned,
only the aggregation results.
+
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:

==== Aggregations Example

For example, given 2 users "june" and "king", each owning 3 API keys:

* one that never expires (invalidated for user "king")
* one that expires in 10 days
* and one that expires in 100 day (invalidated for user "june")

the following request returns the names of valid (not expired and not invalidated) API keys
that expire soon (in 30 days time), grouped by owner username.
