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 APIs on the APIs.io network: Files API and Workflows API. Tagged areas include Company, Quantum Computing, Computational Chemistry, Quantum Chemistry, and Drug Discovery.

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.

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/qc-ware: open an issue to ask a question, or submit a pull request to add artifacts.
