Zolo

Zolo is one of Canada's largest national residential real estate marketplaces and a licensed brokerage, operating as Zolo Ventures Ltd. with provincial brokerage subsidiaries — Zolo Realty (Ontario), (Alberta), (British Columbia), (Saskatchewan), (Manitoba) and (Quebec) Inc. — plus Zolo Mortgages Ltd. and Zolo Mortgages (Alberta) Ltd., all owned by Questrade Financial Group Inc. Founded in 2012 as a digital-first brokerage and headquartered at 1900-5700 Yonge Street in Toronto, Zolo reports over 10 million monthly visitors, 750+ active REALTORS®, and $1.5B+ in annual transaction volume across British Columbia, Alberta, Saskatchewan and Ontario. It sits in the Canadian challenger layer alongside HouseSigma, Wahi and Properly, below CREA — the single national cooperative that operates REALTOR.ca and the Data Distribution Facility (DDF) that syndicates member boards' listings — competing on listing speed, sold-price visibility and home-value tooling over data the boards and CREA control. Its API posture is closed. There is no developer portal, no API program page, no partner or data-licensing page, and no machine-readable API contract of any kind — no OpenAPI, GraphQL, AsyncAPI or MCP surface. The subdomains api., developer., developers., docs., data. and partners.zolo.ca do not resolve in DNS and have never appeared in Certificate Transparency, and every conventional contract path on www.zolo.ca is answered by a Cloudflare bot challenge (HTTP 403, cf-mitigated: challenge) rather than a specification. What Zolo does publish is syndication, not integration: an unauthenticated RSS 2.0 new-listings feed at /rss_new_listings.php, a family of sitemaps.org XML documents, and a site-wide schema.org JSON-LD block carrying organization identity only. Behind the edge it operates an undocumented JSON endpoint at /gallery_map_json.php and two first-party mobile apps (com.ols.zolo) on a private backend. Zolo's own robots.txt declares that RSS feed as a sitemap and a CREA terms-acceptance route at /crea_accept.php, and Section 23 of its Terms of Use is a Virtual Office Website (VOW) clause requiring registration, a bona fide interest in buying or selling, personal non-commercial use only, and an express prohibition on "scraping" (including "screen scraping" and "database scraping"), data mining, redistribution or sublicensing — enforceable directly by CREA, TRREB, ITSO, REBGV, Pillar9 and OREB. Access is licensed, not open. RESO is absent: Zolo is not among the nineteen Canadian organizations RESO lists as members, and no Web API or Data Dictionary certification, OData $metadata document, or Universal Property Identifier (UPI) usage was found. No open, unlicensed dataset is published.

Zolo is profiled on the APIs.io network. Tagged areas include Real Estate, Canada, Property Listings, MLS, and IDX.

The Zolo catalog on APIs.io includes 1 JSON-LD context.

Zolo’s developer surface includes engineering blog, support, legal docs, YouTube channel, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Raise your score.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

13 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 6.7 — up to +23.3 composite points
Developer Ergonomics scores 7.1 — up to +18.6 composite points
Access Clarity scores 21.1 — up to +15.8 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/zolo/apis.yml: open an issue on github.com/api-evangelist/zolo to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Consumer Lending Licensing (UK, US, Canada credit licence registers)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
