# 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 [In-Memory DB documentation](https://redis.io/docs/latest/develop/connect/cli/).
{% endhint %}
## Endpoint
Use a [region-specific endpoint](/cloud/databases/in-memory-db/api/v1-api.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 %}
{% tab title="Request Header Parameters" %}

| Header Parameters | Required | Type | Description |
| ----------------- | :------: | :----: | ------------------------------------------------------------ |
| `Authorization` | yes | string | Provide a header value as `Bearer` followed by your `token`. |
| `Content-Type` | yes | string | Set this to `application/json`. |
| {% endtab %} | | | |
{% tab title="Path Parameters" %}
The following path parameter is mandatory:
| Path Parameter | Required | Type | Description |
| -------------- | :------: | :----: | --------------------------------------------------------------------------------- |
| `replicasetId` | yes | string | The ID (UUID) of the ReplicaSet. Example: `498ae72f-411f-11eb-9d07-046c59cc737e`. |
| {% endtab %} | | | |
| {% endtabs %} | | | |

## Querying This Documentation
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, and the optional `goal` query parameter:
```
GET https://docs.ionos.com/cloud/databases/in-memory-db/api/v1-api/fetch-in-memory-db-instance.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
