What api-documentation-generator does

Inspects server route declarations directly from your repository. It outlines HTTP methods, path variables, payload validations, and expected response codes. This helps when onboarding teammates or sharing public guides.

Produces call examples in cURL and JavaScript. It also documents authentication flows, pagination parameters, rate limits, and failure responses.

Can prepare an OpenAPI specification if needed. Precise outputs require Claude Code to access your router and model source files.

What it helps with

  • inspect source code to document routes, parameters, and responses
  • create reproducible request samples in cURL and JavaScript
  • build error resolution guides with specific status codes
  • export OpenAPI specifications and Postman collections from endpoints

Example prompts for the agent

  • Inspect the routes in src/api and build an API reference document
  • Document our auth endpoints with token refresh steps and cURL snippets
  • Generate an OpenAPI spec based on the controllers in this repository
