I'm building with the RealtyCrawl API. It returns real-estate data from Zillow as typed JSON: homes for sale, sold homes, rentals, property history, estimates and comps. Read the docs first: https://realtycrawl.com/llms.txt OpenAPI spec: https://realtycrawl.com/openapi.json Rules for the code you write: - Base URL: https://api.realtycrawl.com/v1 - Auth: send the header "Authorization: Bearer <key>". Read the key from the REALTYCRAWL_KEY environment variable. Never put it in browser code. - Zillow sold homes: GET /zillow/sold?zip=<5-digit ZIP>&sold_within_days=90. You can send city and state instead of zip. - A call often answers 202 with status "pending" and a poll_url. Poll GET /jobs/<request_id>?wait=20 with the same header until status is "complete" or "failed". - The rows are in result.data, each with address, sale_price, sold_date, sale_price_disclosure and source_url. sale_price is null when the price isn't public; result.field_notes says why. Never replace a null with a guess. - result.summary has median_sale_price and median_price_per_sqft. For the next page, send result.next_cursor as cursor. - A search costs 1 credit; property details and comps cost 2. A free account starts with 100 credits that do not refill, so save results while testing instead of repeating a call. Start with a short script that prints the median sale price for ZIP "80221". Then ask me what I want to build.
It depends on the data. For listings, sold homes, price history and the portals' own estimates from Zillow, Redfin, Realtor.com, StreetEasy and Auction.com, RealtyCrawl starts lowest at $9 a month. For county records like owners and deeds, RentCast is built on public records. For many sources beyond these five, RealtyAPI lists 33.
Not one you can sign up for. Zillow retired its public API in September 2021, and its current data access goes through partner approval.
No one can. In non-disclosure states such as Texas and Utah, sale prices aren't public. RealtyCrawl returns null with a reason there, and RentCast's docs say the same about its records.
