RESO does not provide MLS real estate data. RESO creates the standard for the data, and other organizations build technology based upon it. Brokers and technology companies should go directly to MLSs to request data via the Web API. MLSs owned and operated by REALTOR® associations are required by the National Association of REALTORS® to have production-level access available to their data via Web API.
We have constructed and will continue to work on a Developer’s FAQ that will answer most questions related to the Web API and other standards. RESO standards are always in a state of growth. Useful Web API tools and examples can be found at RESO Web API Tools & Software.
