We built the resource we wished existed when we were first learning to work with APIs — a single, well-organized, always-free directory of public APIs you can actually use.
Learning to build with APIs shouldn't cost money. When you're starting out, you just need working endpoints you can call, real JSON responses to parse, and clear documentation to follow. APITestingFree.com exists to make that as easy as possible.
We curate and organize over 1,500 free public APIs so that developers at every skill level — from someone writing their very first fetch() call to experienced engineers prototyping a new product — can find exactly what they need without hunting across dozens of disconnected lists and blog posts.
Our API directory is sourced from the public-apis GitHub repository, one of the most starred repositories on GitHub with over 300,000 community stars. The repository is maintained by a global community of developers who contribute, verify, and update API listings.
All data is fetched live from the community's maintained JSON database, ensuring our directory stays up-to-date as APIs are added, updated, or deprecated by the community.
A free API for testing is any publicly accessible web service that returns structured data (usually JSON) over HTTP — at zero cost. These APIs are the backbone of modern developer education. They let you practice the most important real-world skills:
Without free public APIs to practice with, learning these skills would require setting up your own backend server — a significant barrier for beginners. Free test APIs remove that barrier entirely.
Have an API to suggest? Found a broken link? Want to contribute a tutorial? We welcome community contributions. The underlying API data is maintained through the public-apis GitHub repository — open a pull request there to add or update an API listing.
