+GET `https://api.robusta.dev/api/query/report`
+--------------------------------------
+
+Use this endpoint to retrieve aggregated alert data, including the count of each type of alert during a specified time range. Filters can be applied using query parameters such as `account_id` and the time range.

+
+.. list-table::
+   :widths: 20 10 70 10
+   :header-rows: 1

+     - Type
+     - Description
+     - Required
+   * - ``account_id``
+     - string
+     - The unique account identifier (found in your ``generated_values.yaml`` file).
+     - Yes
+   * - ``start_ts``
+     - string
+     - Start timestamp for the query (in ISO 8601 format, e.g., ``2024-10-27T04:02:05.032Z``).
+     - Yes
+   * - ``end_ts``
+     - string
+     - End timestamp for the query (in ISO 8601 format, e.g., ``2024-11-27T05:02:05.032Z``).
+     - Yes
+
+
+Example Request
+^^^^^^^^^^^^^^^
+
+The following `curl` command demonstrates how to query aggregated alert data for a specified time range:
+
+.. code-block:: bash
+
+    curl --location 'https://api.robusta.dev/api/query/report?account_id=XXXXXX-XXXX_XXXX_XXXXX7&start_ts=2024-10-27T04:02:05.032Z&end_ts=2024-11-27T05:02:05.032Z' \
+    --header 'Authorization: Bearer TOKEN_HERE'
+
+
+In the command, make sure to replace the following placeholders:
+
+- **`account_id`**: Your account ID, which can be found in your `generated_values.yaml` file.
+- **`TOKEN_HERE`**: Your API token for authentication. Generate this token in the platform by navigating to **Settings** -> **API Keys** -> **New API Key**, and creating a key with the "Read Alerts" permission.
+
+
+
+Request Headers

+   :header-rows: 1
+
+   * - Header
+     - Description
+   * - ``Authorization``
+     - Bearer token for authentication (e.g., ``Bearer TOKEN_HERE``). The token must have "Read Alerts" permission.
+
+Response Format
+^^^^^^^^^^^^^^^
+
+The API will return a JSON array of aggregated alerts, with each object containing:
+
+- **`aggregation_key`**: The unique identifier of the alert type (e.g., `KubeJobFailed`).
+- **`alert_count`**: The total count of occurrences of this alert type within the specified time range.
