Cloud Endpoints 提供了配额功能，这有助于您控制应用调用 API 的速率。通过设置配额，您可以指定用量限额，以免 API 收到调用应用的过多请求。请求过多可能是由于简单的拼写错误所致，也可能是由于低效系统对您的 API 进行不必要的调用所致。无论是何种原因，您都应在来自特定来源的流量达到某一级别时阻止该流量，这是保证 API 总体运行良好所必需的。通过设置配额，您可以确保一个应用不会对使用您的 API 的其他应用产生负面影响。

Setting a quota allows you to specify usage\nlimits to protect your API from an excessive number of requests from\ncalling applications. The excessive requests might have been caused\nby a simple typo or from an inefficiently designed system that makes needless\ncalls to your API. Regardless of the cause, blocking traffic from a specific\nsource once it reaches a certain level is necessary for the overall health of\nyour API. By setting a quota, you ensure that one application cannot negatively\nimpact other applications that use your API.\n\nTo learn more about quotas, see the \"About Quotas\" page in the documentation for\nyour API implementation:\n\n- [Endpoints OpenAPI documentation](/endpoints/docs/openapi/quotas-overview)\n- [Endpoints gRPC documentation](/endpoints/docs/grpc/quotas-overview)\n- [Endpoints Frameworks documentation](/endpoints/docs/frameworks/quotas-overview)"]]
