Top API Integration For Real Estate

Tech innovations have changed a lot of industries, including real estate. These days, there are a lot of tech-savvy solutions on the market. To create a competitive product in a short time, you need to integrate various APIs and other tools.

In this guide, we’ve collected the top real estate APIs that help speed up the development process and meet deadlines.

Dealing With Data

The real estate apps process a lot of information. Creating a solution, you need to consider the data sources. Any real estate website has various information from floor to district.

For example, a US-based company called Zillow receives data from different sources:

  • Listings made by users;
  • Listings made by agents.

Also, the top real estate companies can get data from brokers, partners, and third-parties.

There is one more information source — MLS or Multiple Listing Service. It’s utilized by a group of real estate agents to see the listings of available properties. This tool can be integrated into your real estate app or website. However, it’s quite tricky to get access to MLS.

Fortunately, there are various APIs that can assist in solving this issue. However, before discussing these APIs, let’s discuss how to integrate MLS databases into your service.

To integrate an exchange of data between your product and MLS, you should set up the Internet Data Exchange.

There are several ways:

  • It’s possible to use the FTP protocol. However, choosing this variant, you need to transfer complete datasets.
  • The next way is to use the Real Estate Transaction Standard. The primary purpose of this framework is to facilitate the exchange of MLS data.

The main point here, you should consider a powerful server-side if you want to build a real estate website. Such a solution allows managing the information and guarantees stable work.
