4. API Endpoints

# Health check
curl http://localhost:9000/api/v1/health

# Authentication
curl -X POST http://localhost:9000/api/v1/auth/register \
  -H "Content-Type: application/json" \
  -d '{"username":"testuser","email":"test@example.com","password":"TestPass123!"}'

# Model listing
curl http://localhost:9000/api/v1/models

# Text generation (requires auth token)
curl -X POST http://localhost:9000/api/v1/generate \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"Hello world","model":"gpt-3.5-turbo"}'
