# Retrieve an index

GET https://api.twelvelabs.io/v1.3/indexes/{index-id}

This method retrieves details about the specified index.


Reference: https://docs.twelvelabs.io/api-reference/indexes/retrieve

## Authentication

- `x-api-key` header (required) — Your API key. You can find your API key on the API Keys page.

## Request

### Path parameters

- `index-id` (string, required) — Unique identifier of the index to retrieve.

## Response

### 200

The specified index has successfully been retrieved.

- `_id` (string, optional) — A string representing the unique identifier of the index. It is assigned by the platform when an index is created.
- `created_at` (string, optional) — A string representing the date and time, in the RFC 3339 format ("YYYY-MM-DDTHH:mm:ssZ"), that the index was created.
- `updated_at` (string, optional) — A string representing the date and time, in the RFC 3339 format ("YYYY-MM-DDTHH:mm:ssZ"), that the index has been updated.
- `expires_at` (string, optional) — A string representing the date and time, in the RFC 3339 format ("YYYY-MM-DDTHH:mm:ssZ"), when your index will expire. If you're on the Free plan, the platform retains your index data for 90 days from creation. After this period, the platform deletes your index data, and this action cannot be undone. To continue using your index beyond this period, consider upgrading to the Developer plan, which offers unlimited index retention. For details, see the [Upgrade to the Developer plan](/v1.3/docs/get-started/manage-your-plan#upgrade-to-the-developer-plan) section. If you're on the Developer plan, this field is set to `null`, indicating no expiration.
- `index_name` (string, optional) — A string representing the name of the index.
- `total_duration` (double, optional) — A number representing the total duration, in seconds, of the videos in the index.
- `video_count` (double, optional) — The number of videos uploaded to this index.
- `models` (list of IndexModelsItems, optional) — An array containing the list of the [video understanding models](/v1.3/docs/concepts/models) enabled for this index.
- `addons` (list of string, optional) — The list of the add-ons that are enabled for this index.

## Errors

### 400 Bad Request Error

The request has failed.

- `code` (string, optional) — A string representing the code associated with the error. See the [Error codes](/v1.3/api-reference/error-codes) page for details.
- `message` (string, optional) — A human-readable string describing the error, intended to be suitable for display in a user interface.

## Types

### IndexModelsItems

- `model_name` (string, optional) — A string representing the name of the model.
