  title: Amazon Kinesis Data Streams Account Shards API
  description: Amazon Kinesis Data Streams is a massively scalable and durable real-time data streaming service. It can continuously capture gigabytes of data per second from hundreds of thousands of sources such as website clickstreams, database event streams, financial transactions, social media feeds, IT logs, and location-tracking events. The Kinesis Data Streams API uses a JSON protocol over HTTP with the X-Amz-Target header to specify the action.
