RentCast API
The RentCast API provides programmatic access to US real estate data including 140+ million property records with ownership details, automated valuation model (AVM) rent and home value estimates with comparable properties, active and inactive sale and rental listings across all 50 states, and aggregate market statistics for zip codes. Authentication uses an X-Api-Key header. All endpoints are read-only GET requests.
