What this means for data collection
This is an editorial grouping of saved protection indicators, not a measured scraping success rate or a prediction for a particular request.
No guaranteed IP class. The saved observations include no controlled success-rate test by IP class. They do not establish that mobile, residential or datacenter addresses will be accepted. Request access through the site’s supported API or permission process and evaluate only authorized workloads.
Real Estate & Property Listings: Saved protection observations for Real Estate & Property Listings. Records show the indicators associated with each site; they do not measure an industry-wide success rate or prescribe an IP class.
Responsible use. This page describes the defense that exists, not how to defeat it. Always respect Realtor.com's robots.txt, Terms of Service and applicable law, and collect only data you are permitted to. We do not provide site-specific bypass instructions.

Three ways to collect Realtor.com data
Best when: You have engineers and 1-2 easy targets
- Dedicated 4G/5G carrier IPs, self-serve
- You build, host and maintain the scraper
- Down to $2.40/GB at volume, GB never expire
Best when: Light, unprotected pages at low volume
- You still write the parser and own the breakage
- Per-record cost climbs fast on protected sites
- "Success" billing can still charge for blocked 200s
Best when: 1-3 hard, defended targets like Realtor.com
- A principal engineer builds, runs and repairs it
- Real carrier IPs; we prove it in a paid pilot first
- Delivered as clean CSV / JSON / API - breakage is ours
Data Works is our done-for-you web-data service: you send the URLs and fields, we run the collection on real 4G/5G carrier IPs and deliver clean, QA-checked CSV / JSON / API data. Prefer to run it yourself? The same carrier IPs are self-serve from $4/GB.

Questions
- Does Realtor.com use anti-bot protection?
- Yes. As of July 2026, realtor.com was observed running Kasada. This is an editorial grouping of saved protection indicators, not a measured scraping success rate or a prediction for a particular request.
- What kind of proxy do I need to collect data from Realtor.com?
- The saved observations include no controlled success-rate test by IP class. They do not establish that mobile, residential or datacenter addresses will be accepted. Request access through the site’s supported API or permission process and evaluate only authorized workloads. Whatever you use, respect Realtor.com's robots.txt and Terms of Service and collect only what you are permitted to.
- Why does Realtor.com load fine in my browser but block my scraper?
- The saved indicators do not diagnose an individual blocked request. A browser and an automated client can differ in session state and request behavior; the site’s own logs and access policy are needed to establish a cause.
- Will residential proxies work on Realtor.com?
- This registry has no controlled residential-versus-mobile success test for this site. A vendor indicator cannot establish whether either address class will work.
Signals were recorded from public responses and can change without notice. They say which protection a site ran when observed; they do not predict whether a particular request, client or IP class will be allowed.
