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.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Terra CO2 the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Terra CO2 scores 10.9/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
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.
This is an honest zero, not a gap in our research. Terra CO2 does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Terra CO2
Each block below is one kind of artifact we hold for Terra CO2. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Terra CO2, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
