API Documentation Generator
Generates accurate, up-to-date API references and OpenAPI specifications directly from source code implementations.
API Documentation automates the discovery, extraction, and formatting of REST and GraphQL endpoint documentation directly from your codebase across frameworks like Express, FastAPI, and Gin. By analyzing routes, controller handlers, validation schemas, and authentication middleware, it creates comprehensive endpoint breakdowns, schema tables, working curl examples, and OpenAPI/Swagger specifications to ensure your documentation never drifts from actual production code.
Key Features
01Schema and type extraction from TypeScript interfaces and validation libraries like Zod and Joi
02Generation of working, copy-pasteable curl examples for fast API testing
0346 GitHub stars
