notes: CloudEvents is an open-source specification, not an API service. There are no rate limits because
  there is no hosted endpoint. Rate limits are enforced by the platforms that implement CloudEvents (Amazon
  EventBridge, Azure Event Grid, Google Cloud Eventarc, Knative Eventing, etc.) — refer to those providers'
  rate-limit documentation.
description: CloudEvents itself is a specification with no hosted API; there is nothing to rate-limit.
  Implementing platforms enforce their own rate limits.
