Sirius

beSirius is an Amsterdam-based AI platform for the critical minerals and metals value chain. It builds a continuously verified digital Twin of every supplier, mapping each company's data to the frameworks, questionnaires, and regulations its buyers, auditors, and regulators require - including CSDDD, CMRT/EMRT/AMRT conflict-minerals reporting, EcoVadis, CDP, S&P CSA, UN Global Compact, LME Passport, and the Consolidated Mining Standard Initiative (CMSI). The platform automates supplier due diligence, sustainability and ESG data collection and verification, certification readiness, customer KYC, and ratings improvement across mining, processing, and trading supply chains, reducing manual audit and disclosure effort. beSirius is backed by Techstars and other investors.

Sirius is profiled on the APIs.io network. Tagged areas include Company, Sustainability, ESG, Critical Minerals, and Supply Chain.

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.

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