The "MetaMask JSON-RPC API Playground" is MetaMask's interactive documentation which lets you view, test and debug MetaMask JSON-RPC API calls. It comes in handy if you're e.g. integrating your frontend with the MetaMask API.

Protip: Click on the "Inspector" tab at the bottom right to intercept and inspect HTTP, WebSocket and MetaMask calls.
