Modern API Solutions for IDX

Stellar MLS offers two API options for IDX: MLS Grid and Bridge API. Both options are RESO Data Dictionary compliant and partner with numerous MLSs across the country to streamline the process of pulling listing data in a standardized and consistent format.

Stellar MLS has chosen to use API options, which are widely used in the web industry, over RETS, which is only serviced by a niche group of vendors. With API, adding a real estate feed to your site is more cost-effective and efficient, because any developer can easily add the feed without learning RETS.

Don't Get Left Behind!

Stellar MLS fully transitions from RETS to API options in 2022.

Stellar MLS is now using API options exclusively for new data feed requests, and we are currently transitioning participating IDX brokers and vendors from outdated RETS agreements.

Once Stellar completes its transition, only customers who have switched from RETS to one of Stellar's API options will be able to pull our data.
