# WebSocket stream

Unlike HTTP, with WebSockets, you don't need to continuously make requests when you want specific information. WebSockets maintain a network connection for you (if done right) and listen for changes . You may view the official documentation [here](https://docs.polygon.technology/docs/edge/get-started/json-rpc-commands/).
