Parameters	Details
API_KEY (required)	User's API Key.
URL (required)	The URL of the Redfin page. The URL has to be the URL of a property for sale.
country_code	Allows you to geotarget the request. Use this parameter if you want Redfin to be scraped from a specific country.
TLD	The top level domain to scrape. Valid options: ‘com’ (for redfin.com) ‘ca’ (for redfin.ca)
raw	This is a boolean param - true or false If the raw parameter is set to true, the raw data will be extracted from the page without further parsing. Important: The structure of the data in raw mode cannot be guaranteed, it’s a tradeoff: You get a lot more information back, but the structure of the response may change if Redfin modifies their page layout.
