The gist

Public APIs is a community-curated GitHub repository listing free APIs for software development. Maintained by contributors and APILayer, it serves as a centralized directory to help developers discover and use publicly available APIs. The collection is organized into dozens of categories, such as business, cryptocurrency, and entertainment, providing a valuable resource for finding data and services to integrate into applications.

What it does

Lists hundreds of free-to-use public APIs across numerous domains.
Categorizes APIs by topic, including business, entertainment, and development.
Provides basic metadata for each API, such as authentication requirements and CORS support.
Links directly to the documentation for each listed API.
Maintains an open-source contribution model for adding or updating listings.

How it works

This resource is delivered as a single, extensive Markdown file within a public GitHub repository. Users navigate the file by scrolling through categorized lists or using their browser's search function to find relevant APIs. Each entry provides a brief description and a link to the API's official documentation. The project is completely free and open-source, relying on community contributions to stay current.

Best for

Developers, students, and hobbyists looking for a comprehensive, centralized directory of free APIs to use in their projects. It is an ideal starting point for discovering a service that provides a specific type of data.

Watch out for

As a community-maintained list, some API links may become outdated or broken over time. The repository does not guarantee the quality or reliability of the listed APIs; users must perform their own evaluation.
