# OpenRouter API key rotation

> Learn how to automatically rotate OpenRouter API keys.

> [!NOTE]
>
> **Rotation Type: Dual-Phase**
>
> This rotation maintains two active credential sets with overlapping validity, ensuring zero-downtime during rotation cycles.

## Prerequisites

* Create an [OpenRouter Connection](https://infisical.com/docs/integrations/app-connections/openrouter.md) using a **Provisioning API key**. That connection is used to create and delete API keys on your behalf during rotation.

## Create an OpenRouter API key rotation in Infisical

> [tab] Infisical UI
>
> 1. Navigate to your Secrets Management Project's Dashboard and select **Add Secret Rotation** from the actions dropdown.
>
>    ![Secrets Management Dashboard](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/generic/add-secret-rotation.png)
>
> 2. Select the **OpenRouter API Key** option.
>
>    ![Select OpenRouter API Key](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/select-openrouter-api-key.png)
>
> 3. Configure the rotation behavior, then click **Next**.
>
>    ![Rotation Configuration](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/configuration.png)
>
> * **OpenRouter Connection** – The connection (with a Provisioning API key) that will create and delete API keys during rotation.
>
> * **Rotation Interval** – The interval, in days, after which a rotation is triggered.
>
> * **Rotate At** – The local time of day when rotation runs once the interval has elapsed.
>
> * **Auto-Rotation Enabled** – Whether to rotate automatically on the interval. Turn off to rotate only manually or pause rotation.
>
> 4. Set the OpenRouter API key parameters, then click **Next**.
>
>    ![Rotation Parameters](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/parameters.png)
>
> * **Workspace** (optional) – The OpenRouter workspace to create keys in, which you can't change after you create the rotation (if you leave this blank, OpenRouter uses your Default workspace)
>
> * **Key name** – Display name for the key in OpenRouter (required).
>
> * **Limit** (optional) – Spending limit in USD for this key.
>
> * **Limit reset** (optional) – How often the limit resets: daily, weekly, or monthly.
>
> * **Include BYOK in limit** (optional) – When enabled, usage from your own provider keys ([BYOK](https://openrouter.ai/docs/guides/overview/auth/byok)—Bring Your Own Key) counts toward this key's spending limit. When disabled, only OpenRouter credits are counted. See [OpenRouter BYOK](https://openrouter.ai/docs/guides/overview/auth/byok) for details.
>
> 5. Specify the secret name that the rotated API key will be mapped to. Then click **Next**.
>
>    ![Rotation Secrets Mapping](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/secrets-mapping.png)
>
> * **API Key** – The name of the secret in Infisical where the rotated API key value will be stored.
>
> 6. Give your rotation a name and description (optional). Then click **Next**.
>
>    ![Rotation Details](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/details.png)
>
> * **Name** – A slug-friendly name for this rotation configuration.
>
> * **Description** (optional) – Notes about this rotation.
>
> 7. Review your configuration, then click **Create Secret Rotation**.
>
>    ![Rotation Review](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/review.png)
>
> 8. Your **OpenRouter API Key** rotation is created. The current API key is available as a secret at the mapped path. Rotations will create a new key, switch the active secret to it, then revoke the previous key for zero-downtime rotation.

## Include BYOK in limit (optional)

**BYOK** (Bring Your Own Key) on OpenRouter lets you use your own provider API keys (e.g. OpenAI, Anthropic) so you pay providers directly; OpenRouter charges a small fee on those requests. The **Include BYOK in limit** option controls whether that BYOK usage counts toward this key's spending limit:

* **Enabled (Yes)** – Usage from your own provider keys is included in the limit. Once the limit is reached, the key is subject to OpenRouter's rate limits until the next reset.
* **Disabled (No)** – Only OpenRouter credit usage counts toward the limit. BYOK usage is tracked separately and doesn't consume the limit.

This is optional; if you don't use BYOK or don't set a limit, you can leave it off. For more details, see [OpenRouter BYOK](https://openrouter.ai/docs/guides/overview/auth/byok) and [OpenRouter limits](https://openrouter.ai/docs/api/reference/limits).
