# Ping

Cloud-API and Go Gateway provide a WebSocket **`ping`** request that can be used to measure the latency from the endpoint and to keep the WebSocket connection alive.

**`bdnBlocks`** is a stream of all new blocks as they are propagated in the BDN. The blocks published in the **`bdnBlocks`** stream may include blocks that will not be accepted on chain. This stream offers significant performance speed over the **`newBlocks`** stream (from the Gateway or the node).

Service available on both Cloud API and Gateway-API.

## Stream Endpoint

* Method: `ping`
* Endpoint: `https://tools.bloxroute.com`
