Rentcast

Real estate data API providing property records, rental listings, automated valuations (AVMs), and market statistics for U.S. residential properties. Best for real estate analysis workflows — property valuation, rental market research, and investment due diligence. Unlike financial data providers (SEC EDGAR, Nasdaq), Rentcast focuses specifically on the residential property market. 10 endpoints available through Lava’s AI Gateway. See the Rentcast API docs for full documentation.

Supports both managed (Lava’s API keys) and unmanaged (bring your own credentials) mode.
