This site offers support for developers using the RETS servers FBS provides to customers of its flexmls™ system. To learn more about FBS's API offerings contact us at visit our Spark® API documentation or RESO Web API documentation pages, or register for a demo account at. Additionally, if desired a developer can forego replicating data locally and instead make "live" calls to an API on the fly - resulting in savings on both hosting and infrastructure costs.

The primary driving force behind an API is the ability to not only retrieve many different kinds of data (listings, roster, contacts, saved searches, etc), but easily write that data back into the MLS system, thus creating deeper integrations with third party products. Due to a number of technological limitations the industry is shifting away from RETS to a more modern solution APIs. RETS is a legacy real estate data standard based on XML that allows a developer to retrieve listing and roster data from an MLS system and replicate it to their own local database.
