RentCache: Smart Caching Layer

Property data doesn't change frequently — tax records update annually, ownership changes are rare, and valuations shift gradually. Our intelligent caching proxy, RentCache, stores API responses to dramatically reduce costs while maintaining data freshness.

  • Identical requests served from cache instantly
  • Configurable TTL based on data volatility
  • Per-brokerage API key support for billing transparency
  • Admin dashboard with cache metrics and cost tracking
