API Documentation

Problem

The API lacks comprehensive documentation:

  • No auto-generated OpenAPI/Swagger UI
  • Health endpoint is minimal (only checks database)
  • Missing endpoint documentation and docstrings
  • No API README for developer onboarding
  • No Architecture Decision Records (ADRs)

Solution

Provide comprehensive API documentation:

  1. Auto-generated OpenAPI docs - FastAPI native /docs and /redoc endpoints
  2. Enhanced health checks - /health with full system status, /health/db for database
  3. Endpoint documentation - Proper docstrings, Pydantic models, response codes
  4. API README - Developer onboarding guide
  5. Architecture Decision Records - Document key architectural choices

Key Features

OpenAPI Documentation

  • Interactive Swagger UI at /docs
  • ReDoc at /redoc
  • All endpoints with schemas and examples
  • Authentication documented

Health Monitoring

  • /health - Overall system health (database, disk, uptime)
  • /health/db - Database-specific health check
  • JSON responses with status indicators

Developer Documentation

  • apps/api/README.md - Setup, env vars, testing
  • ADRs in docs/architecture/decisions/
  • Inline code documentation

Benefits

  • Developer onboarding - New devs can understand the API quickly
  • API discoverability - Interactive docs for testing endpoints
  • Health monitoring - Operations can monitor system health
  • Knowledge preservation - ADRs capture why decisions were made

Success Criteria

  • /docs loads Swagger UI with all endpoints
  • /health returns comprehensive health data
  • /health/db returns database status
  • All endpoints have docstrings
  • API README exists with setup instructions
  • At least one ADR exists
