Kiota is a command line tool for generating HTTP API clients from OpenAPI descriptions.

The tool solves the problem of API client fragmentation by generating strongly typed SDK code directly from OpenAPI specifications, eliminating the need to maintain separate dependencies for each API. Rather than writing custom client code or adopting a different library for every HTTP API, developers provide an OpenAPI description and Kiota generates a complete, type-safe client in their language of choice. The generator builds on the Microsoft.OpenAPI.NET library to ensure comprehensive support for OpenAPI and JSON Schema features.

Kiota suits teams that work with multiple APIs and want a consistent, generated client experience across them. It is particularly valuable when you need strongly typed API interactions without learning a new SDK for each service. The tool supports multiple languages including C#, TypeScript, Python, Java, Go, PHP, and Ruby, making it applicable across diverse technology stacks. Developers should verify that their target language is supported and that their APIs have complete OpenAPI descriptions before adoption.

The project maintains active development across its codebase with regular updates to language generators and core functionality. Work spans multiple supported languages simultaneously, indicating sustained effort to keep all code generation targets current. The project engages with community contributions and maintains comprehensive documentation covering both conceptual guidance and practical usage parameters.
