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 8.18 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 May 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

This API gets the current autoscaling capacity based on the configured autoscaling policy. It will return information to size the cluster appropriately to the current workload.
The required_capacity is calculated as the maximum of the required_capacity result of all individual deciders that are enabled for the policy.
The operator should verify that the current_nodes match the operator’s knowledge of the cluster to avoid making autoscaling decisions based on stale or incomplete information.
The response contains decider-specific information you can use to diagnose how and why autoscaling determined a certain capacity was required. This information is provided for diagnosis only. Do not use this information to make autoscaling decisions.

}The compact and aligned text (CAT) APIs aim are intended only for human consumption using the Kibana console or command line. They are not intended for use by applications. For application consumption, it's recommend to use a corresponding JSON API.

]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.

Values are nanos, micros, ms, s, m, h, or d.
If true, returns HH:MM:SS and Unix epoch timestamps.
