- Comprehensive FastAPI server proxying all Rentcast API endpoints - Intelligent caching system with soft delete and stale-while-revalidate - Multi-backend support (SQLite, Redis) with sophisticated cache management - Rate limiting per API key and endpoint with exponential backoff - Rich CLI for administration: API keys, cache management, health checks - SQLAlchemy models: CacheEntry, APIKey, RateLimit, UsageStats - Production middleware: CORS, compression, logging, error handling - Health and metrics endpoints for monitoring - Complete test suite (32% coverage, model tests passing) - Cost management with usage tracking and estimation Features: - Mark cache invalid instead of delete for analytics - Serve stale cache on API errors - Per-endpoint TTL configuration - Rich CLI with colors and tables - Comprehensive monitoring and analytics
