From brokers to government agencies, many companies and professionals often need quick access to reliable, up-to-date real estate information. And APIs are particularly useful if you’re looking to fuel your website or application with property and real estate data — allowing you to easily import the data you need — as and when you need it.

An API (also known as an Application Programming Interface) transfers real estate data from a third-party provider to a website or application. In this post, we explore 9 of the best real estate APIs to help you access comprehensive real estate data in 2022.

Why use a Real Estate API

An API gives you fast, secure access to accurate, up-to-date real estate and property information. You can use a real estate API to automatically update your website or app with real-time property and real estate information.

Depending on your needs, you can use real estate APIs to access a host of different real estate data — from the MLS to neighborhood and crime data. You can then use this information to help boost your SEO and generate more site traffic, provide property and neighborhood information to clients and customers, automate forms, and power analytics.
