Real Estate Aggregator

Scrape US real estate listings from Zillow, Redfin, Realtor.com, Zumper, and Apartments.com at once

Real Estate Aggregator searches five US listing sites for one location in a single run and returns every result in the same format: Realtor.com, Apartments.com, Zumper, Zillow, and Redfin. Give it a ZIP code or a city and choose rent or sale. It queries each site that covers that offer type, normalizes the listings into one schema, and can remove the same home when it appears on several sites.

What you get

One dataset row per listing, with the same fields whichever site it came from:

Field	What it holds
source	The provider it came from, the listing url there, its localId, and scrapedAt
offerType, propertyType, propertyTypeRaw	Rent or sale, the normalized property type, and the site's own label
price	The asking price or rent
bedrooms, bathrooms, livingArea, landArea, areaUnit	Size, in square feet or square meters
address, gps	Street, city, state, ZIP, county, and coordinates
title, description, pictures	The listing text and photos
extras	Days on market, HOA, and the site-specific data that does not fit the shared fields

With includeDetails on, each site reads the listing's own page and adds:

Field	What it holds
yearBuilt, numberOfStories, numberOfUnits	Building facts
schools	Nearby schools with rating and distance
amenities	Features grouped the way the site groups them

Some sites also add site-specific data under extras.providerData, such as price history and tax records (Redfin), sale history (Realtor.com), open houses (Redfin, Realtor.com), and agent contacts (Redfin, Realtor.com, Zumper). Which fields are filled depends on the site and the listing.

Which sites cover what

Site	Rent	Sale	Details
Realtor.com	Yes	Yes	Yes
Zillow	Yes	Yes	Yes
Redfin	Yes	Yes	Yes
Apartments.com	Yes	No	Yes
Zumper	Yes	No	Yes

For a sale search, Apartments.com and Zumper are skipped and the run log says so.

How to run it in Apify Console

1. Open Real Estate Aggregator and enter a location, such as 90210 or Austin, TX.
2. Choose offerType: rent or sale.
3. Optionally pick the providers, set maxResults per site, and turn on includeDetails or deduplicateResults.
4. Start the run and export the dataset as JSON, CSV, or Excel.

It searches one location per run. For several locations, start one run for each.

Input

Field	Type	What it does
location	string	One place name, ZIP code, or postcode. Required
offerType	string	rent or sale. Default sale. Required
providers	array	Which sites to search: realtor, apartments, zumper, zillow, redfin. Default all five
maxResults	integer	The most listings from each site. Default 100
includeDetails	boolean	Read each listing's own page for richer records. Default false
deduplicateResults	boolean	Remove listings that appear on several sites, matched on offer type, country, ZIP, and street, keeping the first. Default false
units	string	imperial (square feet, the default) or metric (square meters)
propertyTypes	array	Any of house, condo, apartment, townhouse, land, multifamily, other. Applied on Realtor.com and Redfin; other sites return all property types
radiusMiles	number	Search radius around the location. Applied on Realtor.com only; other sites ignore it

The smallest input that works:

{
  "location": "90210",
  "offerType": "sale"
}

Rentals in one city, all sites, duplicates removed:

{
  "location": "Austin, TX",
  "offerType": "rent",
  "maxResults": 200,
  "deduplicateResults": true
}

Call it from code, or from an AI agent

Start a run with the Apify API and read the listings when it finishes:

curl -X POST "https://api.apify.com/v2/acts/tri_angle~real-estate-aggregator/runs" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"location": "90210", "offerType": "sale", "deduplicateResults": true}'

The response carries the run's defaultDatasetId. Read the listings from https://api.apify.com/v2/datasets/{defaultDatasetId}/items once the run has finished. A run queries several sites, so start it asynchronously like this.

To let an agent use it, connect Apify's MCP server at https://mcp.apify.com in Claude, Cursor, or any MCP client and add Real Estate Aggregator as a tool. The agent gets one comparable set of listings for an area instead of five different formats.

What it costs

You pay per event, at the price of your Apify plan:

Event	Free plan	Diamond plan
Actor start	$0.0012	$0.00084
Listing	$0.002	$0.0015
Detailed listing (with includeDetails)	$0.002	$0.0015
Deduplication add-on, once per run	$0.005	$0.003

Five sites with the default 100 listings each can return up to 500 listings, about $1 on the Free plan. Deduplication is charged once per run, however many duplicates it removes.

Limitations

• US listings only, from the five sites above, as they show them at run time.
• One location per run.
• Each site has its own coverage and fields, so some values are empty for some sites.
• Deduplication matches on the address, so a home listed with two different street spellings can survive as two rows.

Troubleshooting

These cover what usually goes wrong.

• No rows from Apartments.com or Zumper. They cover rentals only. Set offerType to rent.
• The same home appears twice. Turn on deduplicateResults.
• A filter seems ignored. propertyTypes is applied only on Realtor.com and Redfin, and radiusMiles only on Realtor.com. Results from the other sites are not filtered. To get only matching types, filter the dataset on propertyType.

For anything else, open an issue on the Actor's Issues tab with your run ID.

Frequently asked questions

These are the questions people ask before their first run.

Is the listing data live?

Yes. Every run searches the sites at the time it runs.

What is the smallest input that works?

A location and an offerType, for example {"location": "90210", "offerType": "sale"}.

What happens when a site has no listings for my search?

That site adds no rows to the dataset.

Can I use it as a real estate API?

Yes. Call it through the Apify API with a JSON input and read the listings back as JSON, in one format for all five sites.

Does it work with MCP and AI agents?

Yes. Add it to Apify's MCP server and any MCP client can run it as a tool.

How much does it cost to scrape 500 listings?

About $1 on the Free plan, plus the start fee, and $0.005 more if you remove duplicates.

Can I search several cities at once?

Not in one run. Start one run per location, for example from a loop in your code or from several saved tasks.

Can I get rentals and homes for sale together?

Run it twice, once with offerType: rent and once with sale.

Is it legal to scrape real estate listings?

Scraping publicly available listing data is generally legal. Agent names and phone numbers can be personal data, which laws such as GDPR protect. Follow each site's terms and ask a lawyer if you are unsure about your use case.
