CREXi (Commercial Real Estate Exchange, Inc.) is a Los Angeles-based commercial real estate marketplace and data platform founded in 2015, operating a sales marketplace, lease marketplace, auction platform, Broker PRO tools and the Crexi Intelligence property-records product. Its API surface is partner-gated rather than self-serve: the Crexi Listing API is a one-way syndication feed that lets MLSs, Realtor Boards, brokerages and data providers push listings into the marketplace (RESO, RETS, WebAPI and XML feeds, synced daily, with Crexi stating 100% compliance with the RESO Data Dictionary and 100+ partner organizations), while the Crexi Exchange API is documented in a password-protected Theneo portal at api-docs.crexi.com and fronted by an API-key-gated Swagger UI at exchange.crexi.com. The platform API host api.crexi.com publishes anonymous OpenID Connect and OAuth 2.0 authorization-server discovery documents.
