http://api.example.comElasticsearch provides REST APIs that are used by the UI components and can be called directly to configure and access Elasticsearch features.
This documentation is derived from the main branch of the elasticsearch-specification repository. It is provided under license Attribution-NonCommercial-NoDerivatives 4.0 International.
This documentation contains work-in-progress information for future Elastic Stack releases.
Last update on Jun 6, 2025.
This API is provided under license Apache 2.0.
The API accepts 3 different authentication methods:
Elasticsearch APIs support key-based authentication. You must create an API key and use the encoded value in the request header. For example:
curl -X GET "${ES_URL}/_cat/indices?v=true" \
-H "Authorization: ApiKey ${API_KEY}"
To get API keys, use the /_security/api_key APIs.
Basic auth tokens are constructed with the Basic keyword, followed by a space, followed by a base64-encoded string of your username:password
(separated by a : colon).
Example: send a Authorization: Basic aGVsbG86aGVsbG8=
HTTP header with your requests to authenticate with the API.
Elasticsearch APIs support the use of bearer tokens in the Authorization HTTP header to authenticate with the API.
For examples, refer to Token-based authentication services

]IMPORTANT: CAT APIs are only intended for human consumption using the command line or Kibana console.
They are not intended for use by applications. For application consumption, use the cluster health API.
This API is often used to check malfunctioning clusters.
To help you track cluster health alongside log files and alerting systems, the API returns timestamps in two formats:
HH:MM:SS, which is human-readable but includes no date information;
Unix epoch time, which is machine-sortable and includes date information.
The latter format is useful for cluster recoveries that take multiple days.
You can use the cat health API to verify cluster health across multiple nodes.
You also can use the API to track the recovery of a large cluster over a longer period of time.
The unit used to display time values.
Values are nanos, micros, ms, s, m, h, or d.
If true, returns HH:MM:SS and Unix epoch timestamps.

]You can also use the API to get the health status of only specified data streams and indices. For data streams, the API retrieves the health status of the stream’s backing indices.
The cluster health status is: green, yellow or red. On the shard level, a red status indicates that the specific shard is not allocated in the cluster. Yellow means that the primary shard is allocated but replicas are not. Green means that all shards are allocated. The index level status is controlled by the worst shard status.
One of the main benefits of the API is the ability to wait until the cluster reaches a certain high watermark health level. The cluster status is controlled by the worst index status.
Comma-separated list of data streams, indices, and index aliases used to limit the request. Wildcard expressions (*) are supported. To target all data streams and indices in a cluster, omit this parameter or use _all or *.
Whether to expand wildcard expression to concrete indices that are open, closed or both.
Supported values include:
all: Match any data stream or index, including hidden ones.open: Match open, non-hidden indices. Also matches any non-hidden data stream.closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.none: Wildcard expressions are not accepted.Values are all, open, closed, hidden, or none.
Can be one of cluster, indices or shards. Controls the details level of the health information returned.
Values are cluster, indices, or shards.
If true, the request retrieves information from the local node only. Defaults to false, which means information is retrieved from the master node.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
Values are -1 or 0.
Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.
Values are -1 or 0.
A number controlling to how many active shards to wait for, all to wait for all shards in the cluster to be active, or 0 to not wait.
Values are all or index-setting.
Can be one of immediate, urgent, high, normal, low, languid. Wait until all currently queued events with the given priority are processed.
Values are immediate, urgent, high, normal, low, or languid.
The request waits until the specified number N of nodes is available. It also accepts >=N, <=N, >N and <N. Alternatively, it is possible to use ge(N), le(N), gt(N) and lt(N) notation.
A boolean value which controls whether to wait (until the timeout provided) for the cluster to have no shard initializations. Defaults to false, which means it will not wait for initializing shards.
A boolean value which controls whether to wait (until the timeout provided) for the cluster to have no shard relocations. Defaults to false, which means it will not wait for relocating shards.
One of green, yellow or red. Will wait (until the timeout provided) until the status of the cluster changes to the one provided or better, i.e. green > yellow > red. By default, will not wait for any status.
Supported values include:
green (or GREEN): All shards are assigned.yellow (or YELLOW): All primary shards are assigned, but one or more replica shards are unassigned. If a node in the cluster fails, some data could be unavailable until that node is repaired.red (or RED): One or more primary shards are unassigned, so some data is unavailable. This can occur briefly during cluster startup as primary shards are assigned.Values are green, GREEN, yellow, YELLOW, red, or RED.

NOTE: This API returns a list of any pending updates to the cluster state. These are distinct from the tasks reported by the task management API which include periodic tasks and tasks initiated by the user, such as node stats, search queries, or create index requests. However, if a user-initiated task such as a create index command causes a cluster state update, the activity of this task might be reported by both task api and pending cluster tasks API.
If true, the request retrieves information from the local node only.

--header "Authorization: $API_KEY"Get information about configured remote clusters. The API returns connection and endpoint information keyed by the configured remote cluster alias.
This API returns information that reflects current state on the local cluster.
The connected field does not necessarily reflect whether a remote cluster is down or unavailable, only whether there is currently an open connection to it.
Elasticsearch does not spontaneously try to reconnect to a disconnected remote cluster.
To trigger a reconnection, attempt a cross-cluster search, ES|QL cross-cluster search, or try the resolve cluster endpoint.
curl \
--request GET 'http://api.example.com/_remote/info' \
--header "Authorization: $API_KEY"Get comprehensive information about the state of the cluster.
The cluster state is an internal data structure which keeps track of a variety of information needed by every node, including the identity and attributes of the other nodes in the cluster; cluster-wide settings; index metadata, including the mapping and settings for each index; the location and status of every shard copy in the cluster.
The elected master node ensures that every node in the cluster has a copy of the same cluster state. This API lets you retrieve a representation of this internal state for debugging or diagnostic purposes. You may need to consult the Elasticsearch source code to determine the precise meaning of the response.
By default the API will route requests to the elected master node since this node is the authoritative source of cluster states.
You can also retrieve the cluster state held on the node handling the API request by adding the ?local=true query parameter.
Elasticsearch may need to expend significant effort to compute a response to this API in larger clusters, and the response may comprise a very large quantity of data. If you use this API repeatedly, your cluster may become unstable.
WARNING: The response is a representation of an internal data structure. Its format is not subject to the same compatibility guarantees as other more stable APIs and may change from version to version. Do not query this API using external monitoring tools. Instead, obtain the information you require using other more stable cluster APIs.
Whether to ignore if a wildcard indices expression resolves into no concrete indices. (This includes _all string or when no indices have been specified)
Whether to expand wildcard expression to concrete indices that are open, closed or both.
Supported values include:
all: Match any data stream or index, including hidden ones.open: Match open, non-hidden indices. Also matches any non-hidden data stream.closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.none: Wildcard expressions are not accepted.Values are all, open, closed, hidden, or none.
