WhatPulse API

⭐ Beginner's Pick Tracking / No Auth Required Beginner HTTPS
Free to Use Varies (check documentation)

Overview

WhatPulse is a free public API that exposes keyboard, mouse, and network usage statistics collected by the WhatPulse desktop application. You can retrieve team and user pulse data without any authentication, making it a great first API to practice with. It returns simple JSON objects that are easy to parse and display.

💡

Beginner Tip

Use your own WhatPulse username to fetch real data and confirm the response format before building anything more complex. The API has no authentication, so you can call it directly from a browser URL bar.
