Redfin Real Estate Scraper - Listings, Price History & Market Data

Scrape Redfin real estate listings by city, ZIP code, address, or landmark. Extract property details, prices, agent info, photos, and price history. Cross-reference with Zillow and Realtor.com using normalized addresses.

What's New

• State input field -- new state field accepts a two-letter state code (e.g., "TX", "NY") and works with the city field for accurate search targeting
• Search URL builder fix -- previously all searches hardcoded California (state=CA, cityId=0), breaking results for every non-CA query. Now properly uses the state from input and falls back to Redfin's search endpoint when state cannot be determined
• "City, ST" format support -- the city field now auto-parses formats like "San Francisco, CA" or "Austin, TX", extracting the state automatically
• Session cookies -- optional sessionCookies field for injecting browser cookies if you encounter access issues
• Cookie injection -- preNavigationHooks inject cookies before each page load for consistent sessions

Important: Rate Limiting Considerations

Redfin monitors for automated access. To minimize detection:

1. Start slow - Begin with maxResults: 20 and increase gradually
2. Use residential proxies - Enabled by default
3. Space your runs - Wait 15-30 minutes between runs
4. Keep batches reasonable - 50-100 listings per run

No account required - This scraper uses public listing data.

Quick Start

Demo Mode (Free Test)

{
  "demoMode": true
}

Search by City + State

{
  "city": "Austin",
  "state": "TX",
  "maxResults": 50,
  "demoMode": false
}

Search by "City, ST" Format

{
  "city": "Seattle, WA",
  "maxResults": 50,
  "demoMode": false
}

The state is auto-parsed from the city field when you use "City, ST" format.

Search by ZIP Code with Filters

{
  "zipCode": "94102",
  "priceMin": 500000,
  "priceMax": 1500000,
  "bedsMin": 2,
  "propertyTypes": ["house", "condo"],
  "maxResults": 50,
  "demoMode": false
}

Recent Listings Near Address

{
  "address": "456 Market St, San Francisco, CA",
  "searchRadius": 2,
  "listedWithin": 7,
  "maxResults": 25,
  "demoMode": false
}

Authentication (Optional)

Redfin data is mostly public and does not require login. However, if you encounter access issues or rate limiting, session cookies can help.

How to Get Cookies

1. Install the Cookie-Editor browser extension (Chrome/Firefox/Edge)
2. Go to redfin.com and browse a few listings
3. Click the Cookie-Editor icon in your browser toolbar
4. Click Export (JSON format) -- this copies all Redfin cookies to your clipboard
5. Paste the JSON array into the sessionCookies input field

Example with Cookies

{
  "city": "Denver",
  "state": "CO",
  "sessionCookies": "[{\"name\":\"RF_BROWSER_ID\",\"value\":\"...\",\"domain\":\".redfin.com\"}, ...]",
  "demoMode": false
}

Without Cookies

• Public listings work out of the box
• May encounter rate limiting on large batches

With Cookies

• More consistent access across multiple runs
• Reduces chance of being rate limited

city only (no state)	city: "Miami"	Falls back to Redfin search endpoint
zipCode	zipCode: "94102"	Builds URL /zipcode/94102/filter
address	address: "123 Main St, Seattle, WA"	Uses Redfin address search with radius
landmark	landmark: "Stanford University"	Uses Redfin search endpoint

Address Normalization

Use addressNormalized to deduplicate listings across Redfin, Zillow, and Realtor.com. All three scrapers output USPS-standard formatted addresses:

• Uppercase
• Standard abbreviations (Street -> ST, Avenue -> AVE, Boulevard -> BLVD)
• No punctuation
• Format: STREET, CITY, STATE ZIP

Pricing (Pay-Per-Event)

Event	Description	Price
property_scraped	Per property listing scraped	$0.10

Example costs:

• 50 listings: 50 x $0.10 = $5.00
• 200 listings: 200 x $0.10 = $20.00
• Demo mode: $0.00

Compare to PropStream at $99/mo or CoStar at $500+/mo.

}

Scenario 2: Investment Property Hunting

Official API Alternatives

Redfin does not offer a public API. This scraper is the most practical way to access Redfin data programmatically.

• Realtor.com - Partnership agreements required (see our Realtor Scraper)
• ATTOM Data - Property data API ($500+/mo)

FAQ

Q: Do I need a Redfin account?

A: No. Uses public listing data. Session cookies are optional and only needed if you hit rate limits.

Q: How do I deduplicate across platforms?

A: Use the addressNormalized field -- identical format across Zillow, Redfin, and Realtor scrapers.

Q: Can I get Redfin Estimate values?

A: The scraper extracts publicly visible pricing data. Redfin Estimates are captured when displayed on listing pages.

Q: Do I need to provide a state code?

A: It is recommended for best results. You can either use the separate state field (e.g., "TX") or include it in the city field (e.g., "Austin, TX"). Without a state, the scraper falls back to Redfin's search endpoint which may be less reliable.

Q: Why were my non-California searches returning wrong results?

A: A previous version hardcoded California in the search URL builder. This has been fixed. The scraper now properly uses the state from your input.

Troubleshooting

Problem	Cause	Solution
"No listings found"	Location spelling, filters too narrow	Check location spelling, broaden price/bed/bath filters, try a different search type (ZIP vs. city)
Wrong state results	Missing state field	Add the state field (e.g., "TX") or use "City, ST" format in the city field
"Rate limited"	Too many requests in short time	Wait 15-30 minutes, reduce batch size to 20-50, run during off-peak hours
"Demo data showing"	demoMode still enabled	Set demoMode: false -- no API key or login required
Missing price history	Listing page layout variation	Some listings have limited history. Price history depends on Redfin page structure
Missing agent info	Agent section not on page	Not all listings display agent contact info publicly
Timeout or crash	Large batch or slow network	Reduce maxResults, ensure residential proxy is configured
"Missing required input"	No location provided	Provide at least one of: city, zipCode, address, or landmark
Access blocked	Redfin detecting automation	Add sessionCookies from Cookie-Editor, use residential proxies, reduce batch size
