Real Estate Standards Organization, or RESO, was incorporated in November 2011 as an independent, not-for-profit trade organization that was previously a section of the National Association of REALTORS®.
RESO actively develops, adopts and implements open and accepted data standards and processes across all real estate transactions. Tracking, certifying and encouraging MLSs to adopt the Web API for IDX data is one RESO's top priorities. Distributing IDX data using a live API rather than RETS feed provides a number of benefits to consumers, agents and MLS associations.
AgentSquared is the only IDX website vendor that's powered by a Web API. All other IDX vendors use the old RETS feed standard. AgentSquared is a member of RESO and is working with RESO become RESO certified, and to define and document the client portion of its web API certification program.
