Cloud Endpoints provides quotas, which let you control the rate at which
applications can call your API. Setting a quota allows you to 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. Regardless of the cause, blocking traffic from a specific
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.
To learn more about quotas, see the "About Quotas" page in the documentation for
your API implementation:
