Culdesac

Culdesac is a post-car real estate development company building walkable, car-free neighborhoods in the United States. Its first project, Culdesac Tempe in Tempe, Arizona, broke ground in 2019 and welcomed its first residents in 2021 — a 16-acre, roughly $140 million development of 636 apartment units plus 24,000 square feet of restaurant and retail space, designed with no resident parking. Residents receive transportation benefits such as free light-rail rides and discounted rideshare and scooter access in place of car ownership. Culdesac operates leasing, tours, and resident services through its website and HubSpot-backed portals, and intends to replicate the car-free neighborhood model in other cities. It was surfaced as a portfolio company of Initialized Capital and added to the API Evangelist network. Culdesac publishes no public developer API; this profile captures the company identity and domain-security posture.

Culdesac is profiled on the APIs.io network. Tagged areas include Company, Real Estate, Real Estate Development, Housing, and Urban Planning.

Culdesac’s developer surface includes engineering blog, signup flow, support, and 7 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 github.com/api-evangelist/culdesac: open an issue to ask a question, or submit a pull request to add artifacts.
