Get it from the extension manager in VS Code: REST Client by Huachao Mao
GitHub fun is here:

I wanted to include some examples, but then I saw the documentation in VS Code for this extension and it’s very good. Just scroll through the Details tab and get the instructions how to use. It’s quite simple, including, something like GET https://httpbin.org/uuid for a simple get.
