The Canadian Real Estate Association (CREA) is the national industry body for Canadian residential real estate, representing roughly 160,000 REALTORS through some 60 member boards and associations, owning the MLS and REALTOR trademarks in Canada, and operating REALTOR.ca - the country's single national consumer listing portal. Where the United States fragments into roughly 500 independently governed MLSs, Canada consolidates: CREA runs the REALTOR.ca Data Distribution Facility (DDF), one national syndication seam that collects listing content from member boards' MLS Systems and redistributes it to member websites, franchisor pools, and a network of Real Estate Advertising Websites. That makes CREA simultaneously the standards-setter (it writes the DDF Policy and Rules that boards must adopt and enforce), the operator of the pipe, and the gatekeeper of the data. Its API posture is unusually good for an industry body and still firmly gated. Three real machine-readable contracts are downloadable anonymously - an OpenAPI 3.0.4 document for the DDF Web API served from ddfapi.realtor.ca/swagger/v1/swagger.json and embedded in the public Redoc site at ddfapi-docs.realtor.ca, an OpenAPI 3.0.1 document for the REALTOR.ca Board API at boardapi-docs.realtor.ca, and a full OpenID Connect discovery document at identity.crea.ca. The DDF Web API is an OData v4 surface normalized to the RESO Data Dictionary and described by CREA as built on the RESO Web API specification, but CREA is RESO-aligned rather than RESO-certified - it does not appear in RESO's public certification directory of 578 organizations, where the only Canadian entries are individual boards such as the Toronto Regional Real Estate Board and Greater Vancouver REALTORS, none of them Certified Current. Nothing is self-serve. There is no signup, no sandbox and no free tier; client_id and client_secret are, in CREA's own words, provided by CREA. A REALTOR must opt in through the DDF Dashboard on CREA's member portal, and a third-party developer must enter a data access agreement with CREA as a Technology Provider operating a National Pool Website or Member Website on behalf of that opted-in member. The OData $metadata document, the actual RESO contract, returns HTTP 401 to anonymous callers. No open, unlicensed Canadian listing dataset exists behind any of it.
CREA (REALTOR.ca) publishes 6 APIs on the APIs.io network, including Destination API, Lead API, Member API, and 3 more. Tagged areas include Real-Estate, Canada, Property Listings, MLS, and IDX.
CREA (REALTOR.ca)’s developer surface includes authentication, changelog, getting-started guide, documentation, support, engineering blog, and 41 more developer resources.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/crea: open an issue to ask a question, or submit a pull request to add artifacts.
