# OpenRouter API Key

> 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.
</Note>

## Prerequisites

* Create an [OpenRouter Connection](/integrations/app-connections/openrouter) 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

<Tabs>
  <Tab title="Infisical UI">
    1. Navigate to your Secret Manager Project's Dashboard and select **Add Secret Rotation** from the actions dropdown.

    2. Select the **OpenRouter API Key** option.

           <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/select-openrouter-api-key.png" alt="Select OpenRouter API Key" />

    3. Configure the rotation behavior, then click **Next**.

           <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/configuration.png" alt="Rotation Configuration" />

    * **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**.

           <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/parameters.png" alt="Rotation Parameters" />

    * **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**.

           <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/secrets-mapping.png" alt="Rotation Secrets Mapping" />

    * **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**.

           <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/details.png" alt="Rotation Details" />

    * **Name** – A slug-friendly name for this rotation configuration.
    * **Description** (optional) – Notes about this rotation.

    7. Review your configuration, then click **Create Secret Rotation**.

           <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/secret-rotations-v2/openrouter-api-key/review.png" alt="Rotation Review" />

    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.

  </Tab>

  <Tab title="API">
    To create an OpenRouter API Key rotation, call the [Create OpenRouter API Key Rotation](/api-reference/endpoints/secret-rotations/openrouter-api-key/create) API endpoint.

    }
    ```
  </Tab>
</Tabs>

## 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 does not 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).
