CREXi

description: '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.'

  description: The Crexi Exchange API is Crexi's partner-facing REST API, documented in a Theneo-published portal at api-docs.crexi.com
    (password protected) and fronted by a Swagger UI gateway at exchange.crexi.com. The OpenAPI document is served at /swagger/docs/v1
    behind an API-key login gate; the published login script declares the scheme as an apiKey named x-api-key passed in the
    request header.

  description: The api.crexi.com host is the platform API backing the Crexi web and mobile applications. It anonymously publishes
    OpenID Connect discovery (/.well-known/openid-configuration) and OAuth 2.0 authorization server metadata (RFC 8414), exposes
    a JWKS document and a /token endpoint, and returns an ASP.NET Core health-check payload at /health. A Swashbuckle Swagger
    UI is present at /swagger but is protected by HTTP Basic authentication.

  name: Crexi Listing API
  description: The Crexi Listing API is a one-way data sync that lets qualifying organizations — MLSs and Realtor Boards,
    large brokerages and franchise networks, and real estate data providers — automatically push their listings onto Crexi.com.

    Data Dictionary across 100+ partner organizations. Access is granted through integrations@crexi.com after a data and legal
    review, execution of a Listing API agreement, API token issuance and staging-environment testing.
