Frequently Asked Questions
Can I track property price changes over time?
Yes. Schedule recurring API requests to monitor listing price changes, new listings, and delisted properties. Build historical datasets to identify market trends and predict price movements.
Does the API handle property search result pages?
AlterLab renders JavaScript and handles pagination, so you can extract data from search results, map views, and infinite-scroll listing pages that traditional tools cannot access.
