Who We Are

Who

GDX (Global Data Exchange) is a neutral, standards‑first collaboration, sponsored and powered by RealtyFeed, RESO and ADRES and the initial data partners were  Stellar MLS, SNPI (France), ADRES (Abu Dhabi), TRREB (Canada), and SDMLS (San Diego). The entity is being formed by sponsors  as Global Data Exchange, Inc. (Delaware) with trademark filings to protect the brand and ensure continuity. 

What

GDX is a Federated, platform‑agnostic data transport layer that lets qualified real estate organizations share public listing data with each other using RESO standards (Web API + Data Dictionary). Local rules and attribution are preserved; each market remains the source of truth
  • Not an MLS
  • Not a consumer portal
  • Not an exchange program for non‑public data

Why

  • Reduce integration cost and friction by aligning on RESO and a common “clean feed” checklist
  • Improve trust and comparability across borders while respecting local display and policy requirements
  • Create member value with compliant international discovery and referrals—without replacing any MLS

When

  • Delivering the first URL to the data members April 2026
  • Applications for others will open: Q1 2026 when data partners have their URL

Where

Global by design—beginning with the initial geographies (North America, Europe, Middle East) and expanding via a simple, uniform intake process

How

  1. RealtyFeed Inc, will provide the service to initial partners as already managed package
  2. Meet the “clean/valid listings” bar (authorization, quality KPIs, takedown process)
  3. Be RESO‑ready or take that service from GDX to convert: live RESO Web API or commit to RESO membership and certification on a defined clock (3–6 months)
  4. Sign the GDX participation agreement (public‑data scope, display, privacy, audit)
  5. Pilot → Production
