The Ultimate List of Free APIs for Your Next Project

Ever found yourself scouring the internet for a free API to power your side project, only to hit paywalls or outdated docs? The public-apis GitHub repository is here to save you the hassle. With over 350k stars and counting, this community-driven list is a goldmine for developers looking for no-cost APIs across dozens of categories—from weather data to meme generators.

What It Does

The public-apis repo is a massive, manually curated collection of free APIs, neatly organized by category. Need an API for cryptocurrency prices? Animal facts? Flight tracking? It’s all here, complete with descriptions, authentication requirements, and HTTPS support flags. The list is maintained by contributors and sponsored by APILayer, which also offers some premium APIs if you need more robust solutions.

Why It’s Cool

• No fluff, just APIs: The repo cuts straight to the point—no signups, no "contact sales" forms. Just direct links to API docs.
• Community-vetted: APIs are regularly updated or removed if they stop working, so you’re less likely to hit dead ends.
• Postman-ready: Many entries include "Run in Postman" buttons for instant testing.
• Wide variety: Whether you’re building a finance app, a game, or a productivity tool, there’s likely an API here for you.

How to Use It

1. Browse the README: Categories range from Animals to Weather.
2. Check the details: Look for Auth: None if you want zero setup, or note API keys if required.
3. Test it: Use the Postman links (where available) or fire up curl in your terminal.

Final Thoughts

This repo is one of those rare GitHub gems that’s both wildly popular and genuinely useful. Whether you’re prototyping, learning, or just need quick access to data, bookmark this list—it’ll save you hours of Googling. And if you find a missing API? The project welcomes contributions.
