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)."]]
