# Fetch an In-Memory DB Instance

You can retrieve an In-Memory DB instance using its `UUID`. It is found in the response body when an In-Memory DB instance is created or when you retrieve a list of In-Memory DB instances using `GET`.

{% hint style="info" %}
**Note:**

* Remember to update your `UUID`. The sample `UUID` in the example is `498ae72f-411f-11eb-9d07-046c59cc737e`.
* Your instance runs in the default port **6379**. For more information, refer to the [<mark style="color:blue;">In-Memory DB documentation</mark>](https://redis.io/docs/latest/develop/connect/cli/).
  {% endhint %}

## Endpoint

Use a [<mark style="color:blue;">region-specific endpoint</mark>](/cloud/databases/in-memory-db/api-howtos.md#endpoints) from the list to fetch an instance: `https://in-memory-db.{region}.ionos.com/replicasets/{replicasetId}`

## Request

To query a single instance, you need the `id` from your `create` response.

```bash
curl -X 'GET' \
  'https://in-memory-db.de-txl.ionos.com/replicasets/498ae72f-411f-11eb-9d07-046c59cc737e' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer $Token' \
```

{% tabs %}

| Header Parameters | Required |  Type  | Description                                                  |

{% tab title="Path Parameters" %}

| Path Parameter | Required |  Type  | Description                                                                       |
| -------------- | :------: | :----: | --------------------------------------------------------------------------------- |
| `replicasetId` |    yes   | string | The ID (UUID) of the ReplicaSet. Example: `498ae72f-411f-11eb-9d07-046c59cc737e`. |
| {% endtab %}   |          |        |                                                                                   |
| {% endtabs %}  |          |        |                                                                                   |

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.ionos.com/cloud/databases/in-memory-db/api-howtos/fetch-in-memory-db-instance.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
