Public Api Lists
Public API Lists is an open-source, community-maintained curated collection of free public APIs organized into 48 categories. The project is hosted on GitHub and offers a searchable interface, making it easy for developers to browse and filter APIs by category, keyword, or tag. The list is designed to be a comprehensive resource for discovering public APIs for prototyping, learning, or building applications. In addition to the web-based list, the project provides a free JSON API that exposes the entire collection programmatically. This allows developers to integrate the API list into their own tools, dashboards, or automated workflows. The JSON API is updated along with community contributions, ensuring the data remains current. Because the project is open source, anyone can contribute by adding new APIs, correcting outdated entries, or improving categorization. The repository is maintained by a community of developers and is free to use for personal and commercial projects. Overall, it serves as a convenient, centralized starting point for developers seeking free public APIs.
