+  title: Composition API (beta)
+  description: |
+    The Algolia Composition API lets you run search requests on your Compositions.
+
+    ## Client libraries
+
+    Use Algolia's API clients and libraries to reliably integrate Algolia's APIs with your apps.
+    The official API clients are covered by Algolia's [Service Level Agreement](https://www.algolia.com/policies/sla/).
+
+    See: [Algolia's ecosystem](https://www.algolia.com/doc/guides/getting-started/how-algolia-works/in-depth/ecosystem/)
+
+    ## Base URLs
+
+    The base URLs for requests to the Composition API are:
+
+    - `https://{APPLICATION_ID}.algolia.net`
+    - `https://{APPLICATION_ID}-dsn.algolia.net`.
+      If your subscription includes a [Distributed Search Network](https://dashboard.algolia.com/infra),
+      this ensures that requests are sent to servers closest to users.
+
+    Both URLs provide high availability by distributing requests with load balancing.
+
+    **All requests must use HTTPS.**
+
+    ## Retry strategy
+
+    To guarantee high availability, implement a retry strategy for all API requests using the URLs of your servers as fallbacks:
+
+    - `https://{APPLICATION_ID}-1.algolianet.com`
+    - `https://{APPLICATION_ID}-2.algolianet.com`
+    - `https://{APPLICATION_ID}-3.algolianet.com`
+
+    These URLs use a different DNS provider than the primary URLs.
+    You should randomize this list to ensure an even load across the three servers.
+
+    All Algolia API clients implement this retry strategy.
+
+    ## Authentication
+
+    To authenticate your API requests, add these headers:
+
+    - `x-algolia-application-id`. Your Algolia application ID.
+    - `x-algolia-api-key`. An API key with the necessary permissions to make the request.
+      The required access control list (ACL) to make a request is listed in each endpoint's reference.
+
+    You can find your application ID and API key in the [Algolia dashboard](https://dashboard.algolia.com/account).
+
+    ## Request format
+
+    Depending on the endpoint, request bodies are either JSON objects or arrays of JSON objects,
+
+    ## Parameters
+
+    Parameters are passed as query parameters for GET and DELETE requests,
+    and in the request body for POST and PUT requests.
+
+    Query parameters must be [URL-encoded](https://developer.mozilla.org/en-US/docs/Glossary/Percent-encoding).
+    Non-ASCII characters must be UTF-8 encoded.
+    Plus characters (`+`) are interpreted as spaces.
+    Arrays as query parameters must be one of:
+
+    - A comma-separated string: `attributesToRetrieve=title,description`
+    - A URL-encoded JSON array: `attributesToRetrieve=%5B%22title%22,%22description%22%D`
+
+    ## Response status and errors
+
+    The Composition API returns JSON responses.
+    Since JSON doesn't guarantee any specific ordering, don't rely on the order of attributes in the API response.
+
+    Successful responses return a `2xx` status. Client errors return a `4xx` status. Server errors are indicated by a `5xx` status.
+    Error responses have a `message` property with more information.
+
+    ## Version
+
+    The current version of the Composition API is version 1, as indicated by the `/1/` in each endpoint's URL.
