How to Find the Right API on RapidAPI
Search "real estate" on RapidAPI and filter by: category (Data → Real Estate), minimum rating (> 4.0), and free tier availability. Read the endpoint descriptions carefully — many APIs labelled "real estate" are primarily property listing scrapers, not analytics APIs.
