Plan0 Ai

Plan0 AI is a real estate construction technology company that applies AI to preconstruction cost estimation and design analysis. Its platform turns architectural drawings into detailed cost estimates and 3D models in roughly 30 minutes rather than the traditional two-week cycle, and adds automated takeoff and pricing, value-engineering scenario simulation, and predictive analytics. Plan0 AI serves real estate developers underwriting and making preconstruction design decisions, general contractors producing business- development estimates and cost forecasts, and investors validating pro-formas and benchmarking. Surfaced as a Y Combinator portfolio company and added to the API Evangelist network. As of this enrichment pass the company publishes a marketing and demo-booking website only, with no public API, developer documentation, SDKs, or machine-readable API surface.

Plan0 Ai is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Construction, Real Estate, and Cost Estimation.

Plan0 Ai’s developer surface includes pricing, engineering blog, and 4 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/plan0-ai: open an issue to ask a question, or submit a pull request to add artifacts.
