API Documentation Generator
Generate comprehensive API documentation from source code.
Quick Reference
For common documentation patterns, see PATTERNS.md.
Documentation Standards

Process
Step 1: Identify API Endpoints
Look for:
- Route definitions (Express, FastAPI, etc.)
- Controller methods
- Handler functions
Step 2: Extract Information
For each endpoint, extract:
- HTTP method (GET, POST, PUT, DELETE, etc.)
- Path/route
- Parameters (path, query, body)
- Request/response schemas
- Authentication requirements
Step 3: Generate Documentation
Use the template in templates/endpoint.md for consistent formatting.
Step 4: Create Overview
Generate an index of all endpoints with the template in templates/index.md.
Output Formats
Markdown (Default)
Generate markdown documentation suitable for README or docs site.
OpenAPI/Swagger
If requested, generate OpenAPI 3.0 spec. See templates/openapi.yaml for structure.
Examples
See EXAMPLES.md for sample inputs and outputs.
Scripts
To auto-detect routes in common frameworks:
python scripts/detect_routes.py <source_directory>To validate generated OpenAPI spec:
./scripts/validate_openapi.sh <spec_file>
