Realm

Realm is a consumer home-technology company that gives homeowners data-driven insights about their property's value and its renovation potential. The Realm platform combines public property records, permits, zoning, comparable sales, and neighborhood data into personalized recommendations that show which home improvement projects will add the most value, what they are likely to cost, and how they affect a home's estimated worth over time. Marketed at realmhome.com as "Home Renovation Planning & Home Value Insights," the product is delivered as a consumer-facing web and mobile experience rather than a developer platform. Realm was backed by venture investors including DCVC and GGV Capital and is tracked in the API Evangelist network as a company profile.

Realm is profiled on the APIs.io network. Tagged areas include Company, Real Estate, Property Data, Home Improvement, and Home Valuation.

Realm’s developer surface includes engineering blog and 9 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/.

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/realm/apis.yml: open an issue on github.com/api-evangelist/realm to ask a question or point us at an artifact you publish.
