National Association of REALTORS
The National Association of REALTORS (NAR) is the largest trade association in the United States, representing roughly one million members across residential and commercial real estate. NAR is the industry body that sits above the roughly 500 local Multiple Listing Services, and it is the reason the US residential market has a machine-readable contract at all: MLS Policy Statement 7.90 requires MLS organizations owned and operated by associations of REALTORS to implement the RESO Data Dictionary and the RESO Web API and to stay current within one year of each ratification, with compliance demonstrated through the RESO Certification Process. NAR mandates that standard rather than operating it - RESO is a separate organization, and the listing data behind every certified endpoint is licensed through MLS membership, an IDX or VOW agreement, a broker relationship, or a reseller. NAR itself holds no RESO certification and publishes no self-serve developer portal. Its own API surface is REALTORS M1, the members-first engagement system that replaces NRDS: the M1 Gateway External API is a live, HTTP-Basic-authenticated REST API over member, office, association and data-extract records, whose Swagger 2.0 definition and Postman collection NAR publishes openly on GitHub for external association management system vendors and NAR partners, but whose credentials NAR issues only under a partner relationship.
National Association of REALTORS publishes 24 APIs on the APIs.io network, including Association API, Data Extract Request API, Data Extract Schedule API, and 21 more. Tagged areas include Real-Estate, United States, Industry Body, MLS, and RESO.
National Association of REALTORS’s developer surface includes authentication, engineering blog, documentation, support, and 23 more developer resources.
