How to scrape realtor.com and which web scraping API to use

Realtor is the second biggest real estate listing website in the United States based in California with over 100 million monthly users. This makes it one of the most popular real estate targets for web scraping.

Realtor.com is using Kasada anti-bot protection together with proprietary anti-scraping technology to block web scraping. This makes it difficult to scrape Realtor property data reliably and this is where web scraping APIs come in handy.

Overall, only few of web scraping APIs we've tested through our benchmarks perform well for Realtor.com at $2.69 per 1,000 scrape requests on average.

How to scrape realtor.com?

Realtor is one of the easiest targets to scrape as it's a highly efficient javascript application that stores all of its data in JSON format which means headless browser use is not required.

That being said, Realtor.com has a lot of anti-scraping technologies in place, so it's recommended to use a reliable web scraping service that can bypass the constantly changing anti-scraping measures. See benchmarks for the most up-to-date results.

Realtor's HTML datasets contain their data in JSON variables under NextJS framework variables like __NEXT_DATA__ and can be easily extracted for full listing datasets making it an easy scraping target overall.
