Free real estate API

Listingrail's free key returns 100 live listings from any of its 17 portals, once, with no card. That is enough to build and test an integration, not to run one. Below are the other free sources we checked, what each gives for free and what it does not.

Which free option fits

You need current listings. Listingrail or RealtyAPI. Listingrail counts listings returned, so 100 free credits are 100 listings; RealtyAPI counts requests, so its 250 requests can return more rows but some endpoints count double. Both read the portals live.

You need US property records or valuations. RentCast's 50 calls a month or ATTOM's 30-day trial. Both are built around property records and estimates; RentCast also returns US listings.

You need statistics, not rows. The Census Data API for US survey statistics by area, Redfin's Data Center for US market tables, HM Land Registry for sold prices in England and Wales.

You want to run scrapers yourself. Apify's free plan gives $5 of platform usage a month, spent on whichever scrapers you run. Each portal is a separate scraper with its own output.

Use the 100 free listings

One request with your email returns the key; the second spends 20 of the 100 credits on Manchester rentals from Rightmove. Any of the 17 portals works the same way.

curl -X POST https://listingrail.com/v1/signup \
  -H "content-type: application/json" \
  -d '{"email": "you@example.com"}'

# the answer holds your key; then:
curl https://listingrail.com/v1/listings/search \
  -H "Authorization: Bearer re_..." \
  -H "content-type: application/json" \
  -d '{"source": "rightmove", "location": "Manchester", "type": "rent", "limit": 20}'

Or enter your email on the home page. The free key also holds one monitor for daily new-listing alerts.

Questions about free real estate APIs

Is there a free real estate API?

Several, and they give different data. For live listings: Listingrail (100 listings once) and RealtyAPI (250 requests a month). For US property records and estimates: RentCast (50 calls a month) and ATTOM (30-day trial). For official statistics and sold prices: the US Census Data API and HM Land Registry's Price Paid Data, both free.

Is there a free real estate listings API with no credit card?

Listingrail's key needs only an email: 100 listings from any of 17 portals, no card. RealtyAPI's page also says its 250 free requests a month need no card.

Is there a free Zillow API?

Not from Zillow for searching listings: its listing API is invite only and publishes no price. Listingrail's free key returns Zillow listings among its 100, and the Zillow API page has the official details with sources.

How long do the free Listingrail credits last?

The 100 free credits are given once, not every month. Paid plans renew their credits at the start of each billing month. A search that finds nothing, or fails at the portal, uses no credits.

Is there a free real estate API for the UK?

For sold prices, HM Land Registry publishes every sale in England and Wales since 1995 under the Open Government Licence. For current listings, Listingrail's free credits work on Rightmove for sale and to rent.

Can I scrape listings myself instead?

Yes, at the cost of maintaining it. Most large portals refuse requests from cloud servers and change their pages often; the Python guides explain what breaks for each portal and show the API route.

Is there a free real estate API for India or Australia?

Listingrail does not cover India or Australia. Of the free options on this page, RealtyAPI lists Australian sources; check its page for the portals included.
