QC Ware

QC Ware is a quantum and GPU-accelerated computational chemistry company based in Palo Alto, California. Its commercial product is Promethium, a cloud-native quantum chemistry platform that runs ab initio DFT and TD-DFT calculations on NVIDIA A100/V100 GPUs for systems up to roughly 2,000 atoms, used by pharmaceutical and materials-science discovery teams. Promethium exposes a public REST API at api.promethium.qcware.com covering workflow submission (single point, geometry optimization, conformer search, torsion scan, interaction energy / F-SAPT, reaction path and transition state optimization) and a file/project store, plus a Python SDK and a `promethium`/`pm` command-line tool. QC Ware also ran Forge, an earlier quantum computing cloud service with a Python client library, and hosts the Q2B quantum computing conference series.

QC Ware publishes 2 API contracts indexed on the APIs.io network: Files API and Workflows API. Tagged areas include Company, Quantum Computing, Computational Chemistry, Quantum Chemistry, and Drug Discovery.

The QC Ware catalog on APIs.io includes 1 Spectral governance ruleset.

QC Ware’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

7 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 49.0 — up to +12.8 composite points
Operational Transparency scores 18.4 — up to +10.6 composite points
Contract Governance scores 18.2 — up to +9.8 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Life Sciences (Biotech and Pharma R&D)	distribution	9.6 (thin)	-	-
Chemistry and Materials (chemical data depositors, materials-data APIs)	distribution	9.6 (thin)	-	-
Quantum Computing (hardware, cloud and software)	distribution	9.6 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
