Facts API: A Public API for Mocking Data and Practicing REST API Skills
What Is Facts API? As a developer, you often find yourself needing reliable data to test your applications or practice working with REST APIs. Facts API was designed with this in mind—a free and publicly accessible API to help new developers hone their skills, explore how APIs work, and use realistic data for mock projects. This project isn’t just another trivia source. It’s a curated collection of facts, structured in a developer-friendly way, and perfect for learning API integration, data handling, and backend querying. Visit Facts API and experiment freely with real-world API functionality. Why I Created Facts API When I started learning to work with REST APIs, I struggled to find usable endpoints offering data I could experiment with—most options were either too complex or required authentication, limiting my ability to test freely. I built Facts API as a practical solution for new developers, students, and anyone trying to: Understand how REST APIs work. Learn to fetch data, parse JSON responses, and work with structured information. Build projects with realistic mock data. This API is open to the public, free to use, and intentionally simple.
