The MLS Grid is a normalized, RESO-compliant data distribution platform that gives brokers, MLSs, and application vendors a single OData v4 Web API and one master data license agreement covering 50+ participating MLSs across the United States. Built on the RESO Data Dictionary, the MLS Grid Web API standardizes Property, Member, Office, OpenHouse, Media, and Lookup resources for IDX, VOW, broker-only, and product-development use cases, replacing the per-MLS RETS feed sprawl that historically burdened real-estate technology vendors.
