Public-APIs

Public-APIs is a community-maintained directory of web APIs that developers can use when building applications, prototypes, and experiments. It groups services into many categories, including finance, maps, health, machine learning, entertainment, authentication, science, and communication. Each entry provides the API name, a brief explanation, and an indicator for open-source or trial-based access when available. The repository acts as a discovery index rather than an API gateway or software library. Developers can browse the table of contents to find data sources and external capabilities for a specific project. Contributions are accepted through documented repository guidelines and pull requests. Because third-party services can change or disappear, users should verify current documentation, pricing, authentication, and usage limits before integration.
