API Gateway は割り当てを提供します。割り当てを使用すると、アプリケーションが API を呼び出せるペース（レート）を制御できます。割り当てを設定することで、呼び出し元アプリケーションによる過剰な数のリクエストから API を保護するための使用制限を指定できます。過剰な数のリクエストは、単純な入力ミスや、不必要に API を呼び出す非効率的な設計のシステムが原因で発生する場合があります。

Setting a quota lets you specify usage limits to protect your API from an excessive number of requests from calling applications. The excessive requests might have been caused by a simple typo or from an inefficiently designed system that makes needless calls to your API.\n\nRegardless of the cause, blocking traffic from a source once it reaches a certain level is necessary for the overall health of your API. By setting a quota, you ensure that one application cannot negatively impact other applications that use your API.\n| **Note:** For API Gateway, you control quotas as described in the Cloud Endpoints doc at [About quotas](/endpoints/docs/openapi/quotas-overview)."]]
