Public API Finder
Searches for public APIs that match your technical requirements so you don't have to hunt through messy directories.
About This Tool
We built this for developers and product builders who need a specific tool—like a weather API, a flight tracker, or an AI text generator—but don't want to spend hours on GitHub or Postman. It's a discovery engine. It searches the web for APIs and evaluates them based on their documentation, ease of use, and whether they're actually still functional.
It isn't an API manager. It's a research tool to help you find the right external services for your project.
The Problem It Solves
Finding a good API is usually a mess of outdated directories and deprecated repos. Most search results give you options that are either too expensive or don't even work anymore. This app removes that 'discovery friction.' It gives you a curated, researched list of the most reputable APIs available right now.
When to Use This
- You're starting a new project and need a data source (e.g., 'Where can I get real-time currency rates for free?').
- You want to compare providers for the same thing, like 'What's the best alternative to Twilio for what I'm doing?'
- You're looking for an 'Open Source' or 'Public Domain' API that doesn't involve a complex enterprise contract.
How It Works
The app uses an LLM with live search to scan developer forums, GitHub, and API directories. It looks for 'signals' of a high-quality API—like how recently the docs were updated, if there are good community libraries, and what other developers are saying about it.
