Real estate APIs provide real-time data on the housing market. These tools are a great asset for real estate professionals looking to automate updates to listing platforms, apps, or websites, in order to provide clients and customers with reliable and up-to-date real estate data.

In this post, we explore what a real estate API is in more and detail and offer 5 of the leading solutions currently available.

What is a Real Estate API?

Realtyna defines an API as:

“A software tool that acts as an intermediary between an application and the data produced by another application. APIs package functions for retrieving this information, which allows for greater speed and agility with any related programming.”

In the real estate world, an API (also known as an application programming interface) transfers property listing data from the MLS to an agent website or real estate application. Real estate APIs are efficient and fast, retrieving data as and when needed – reducing hosting costs.
