Apiary

Apiary provides a place to design and document APIs before writing code. Define endpoints, specify request and response formats, and generate documentation that stays in sync with your design. Mock servers let frontend developers start building against APIs that don't exist yet. Documentation is interactive—developers test calls directly from the docs. The API Blueprint format is human-readable and version-controllable. When API design happens in Apiary before implementation, teams avoid expensive changes later when they discover the design doesn't work.
