About This Project
This repository serves as a comprehensive directory of publicly available APIs spanning dozens of categories including weather, finance, social media, machine learning, and more. Instead of spending hours researching integration options, developers can quickly discover and evaluate APIs that match their project requirements.
The collection emphasizes practical utility by organizing APIs into logical categories with direct links to documentation. Each entry typically includes authentication requirements, rate limits, and endpoint details, making it easier to assess whether an API fits your technical constraints and budget.
Whether you're prototyping a proof-of-concept or building production features, this list accelerates development by providing a single reference point for discovering third-party services. The community-driven nature means the collection stays current with new APIs and deprecated services are flagged or removed.
With thousands of developers having starred and contributed to this resource, it has become a go-to reference for finding APIs across domains like geolocation, payments, email services, data visualization, and authentication providers.
