> [!CAUTION]
> **Reminder:** To use the Map Management 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.

> [!NOTE]
> **Note:**There's no charge for API usage. API calls appear on the Billing page in the Cloud Console, but charges will be $0.

## Other usage limits

Requests are constrained as follows:

- 3 QPS (queries per second)
- 180 QPM (queries per minute) for a project, refreshed each minute
- 100,000 QPD (queries per day) for a project, refreshed each day

## Authenticating requests

The Maps Management API only supports OAuth, not API keys.

## 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).
