> [!CAUTION]
> **Reminder:** To use the Route Optimization API, you must [enable billing](https://console.cloud.google.com/project/_/billing/enable?utm_source=Docs_BillingNudge) on each of your projects and include an OAuth token with all API or SDK requests.

## Route Optimization API product SKUs

Route Optimization bills **per shipment**, and has two SKUs
that determine the cost. Which SKU is triggered is based on the number of
vehicles in your Route Optimization request:

- Requests that contain **one vehicle**: Billed to the Single Vehicle Routing SKU
- Requests that contain **2 or more vehicles**: Billed to Fleet Routing SKU

> [!IMPORTANT]
> **Important:** The Optimize Tours and Batch Optimize Tours API endpoints serve both Single Vehicle Routing and Fleet Routing requests. The SKU is only determined by the number of vehicles in each request.

The per-request charge is based on the number of shipments in the optimization
request, times the shipment unit price per SKU.

## Adjust quota


Quota limits define the maximum number of requests allowed for a specific API or service within a
given timeframe. When the number of requests in your project reaches the quota limit, your service
stops responding to requests.

> [!IMPORTANT]
> **Important:** To understand how a quota increase might affect your bill, see the [pricing calculator](https://mapsplatform.google.com/pricing/#pricing-calculator).

To modify a quota value for your API, follow these steps:

1. In the Cloud console, go to **Google Maps Platform \> Quotas**.
2. Select the API for which you want to modify the quota.
3. Identify the quota value that you want to change, and select it using the checkbox.
4. Click **Edit** , enter a new quota value, and click **Submit request**.

### View quota increase requests

> [!IMPORTANT]
> **Important:** You must have the appropriate [IAM permissions to view quota increase requests](https://cloud.google.com/docs/quotas/permissions#permissions_increase).

To view all quota increase requests, including past and pending requests, follow these steps:

1. In the Cloud console, go to **Google Maps Platform \> Quotas**.
2. Select the API for which you want to view the quota increase request.
3. Click **Increase Requests**.

> [!TIP]
> **Tip:** Monitor your quota usage regularly to avoid service interruptions. For more information, see [Quotas and quota alerts](https://developers.google.com/maps/billing-and-pricing/manage-costs.md.txt#quotas).
