Terra CO2

Terra CO2 Technology is a Golden, Colorado climate-technology and building-materials manufacturer that produces low-carbon replacements for Portland cement. Its commercial product, OPUS SCM, is a supplementary cementitious material that replaces up to 50% of the Portland cement in a concrete mix as a drop-in substitute for legacy SCMs such as fly ash, cutting CO2 by roughly 70% and NOx by roughly 90% per ton replaced, and it is produced from abundant silicate feedstocks rather than coal-plant by-products. A second product, OPUS ZERO, targets a full zero-carbon cement replacement and is in concrete trials. The company runs a pilot and materials R&D facility in Golden and is building a 240,000-ton-per-year commercial plant in Cleburne, Texas, backed by more than $250M raised from climate and construction investors including Cemex Ventures. Terra CO2 sells physical material into the construction supply chain; it publishes no developer program, no public API, and no machine-readable API contract.

Terra CO2 is profiled on the APIs.io network. Tagged areas include Company, Building Materials, Construction, Cement, and Concrete.

Terra CO2’s developer surface includes support and 8 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/terra-co2: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Terra CO2 Technology manufactures and sells a physical product - OPUS SCM and OPUS ZERO cement replacements shipped
    by the ton into concrete plants - so there is no software product to expose; terraco2.com is a WordPress marketing site
    with no developer portal, no api/developer/docs subdomain resolving in DNS, and no published OpenAPI, GraphQL, MCP or
    agent card.
