Teranet

Teranet Inc. is the private operator of Ontario's Electronic Land Registration System (ELRS) and the POLARIS land records database under a long-running concession with the Government of Ontario, and is the exclusive service provider for Manitoba's Land Titles System and Personal Property Registry. Founded in 1991, headquartered in Toronto and wholly owned by OMERS, Teranet sits at the base of the Canadian property value chain: it holds the authoritative title, parcel, writ and instrument record and resells it as commercial products — Teraview, OnLand, Teranet eXpress, GeoWarehouse, PurView, Teranet Xchange, DataConnect/ValueProtect AVM, TeraIntelligence — plus the Teranet-National Bank House Price Index. Its API posture is licensed access only. Teranet Connect is genuinely described by Teranet as an API (XML and web services over POLARIS and the Writs database), but it is licensed to legal-software vendors through an account manager, with no public documentation, no published base URL, no self-serve signup and no developer portal; Teranet's own support site states plainly that GeoWarehouse has no open API. No RESO certification was found — Teranet is a land registry, not an MLS — and the public record it stewards is sold back rather than published as open data.

Teranet publishes 1 API on the APIs.io network. Tagged areas include Real-Estate, Canada, Land Registry, Title, and Conveyancing.

Teranet’s developer surface includes authentication, changelog, sandbox, engineering blog, support, pricing, signup flow, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector 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/.

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/teranet: open an issue to ask a question, or submit a pull request to add artifacts.

  description: Teranet Connect is described by Teranet as an application programming interface providing secure access to
    Ontario's POLARIS land registration database and the Writs database, using XML and web services interfaces with rules-based

    writ search by debtor name, instrument image retrieval and map data into their own applications. Access is licensed commercially
    through a Teranet account manager; no public technical documentation, base URL, sandbox or self-serve signup is published.
