Nth Cycle

Nth Cycle is a critical mineral refining company headquartered in Beverly, Massachusetts, that recovers production-grade nickel, cobalt, copper and rare earth elements from mined ore, low-grade tailings and recycled industrial scrap. Its patented OYSTER platform uses electro-extraction — an alternative to conventional hydrometallurgy and pyrometallurgy that combines electrochemistry, filtration and chemical precipitation into a single continuous, closed-loop architecture — to deliver modular refining at roughly 70% lower capital intensity, 75% less waste, and economic viability at 5-10x smaller scale than a centralized refinery. Systems install inside existing buildings and can be deployed in as little as two years including permitting, under licensing, build-own-operate tolling, or multi-feedstock off-take models. The company operates the first domestic commercial-scale nickel and cobalt scrap refining system in Fairfield, Ohio, holds a $1.1 billion offtake agreement with Trafigura, was selected by the U.S. Department of Energy for award negotiations of up to $100 million toward a new critical mineral refining facility, and has announced a NYSE listing via business combination with Kensington Capital Acquisition Corp. VI. Enrichment probing on 2026-08-26 found no public developer API, OpenAPI/Swagger/GraphQL/AsyncAPI contract, developer portal, SDK or package-registry entry, CLI, MCP server, A2A agent card, gRPC/Protobuf or WSDL contract, webhook surface, or served /.well-known document — Nth Cycle is a materials refining company, not an API provider.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities 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/nth-cycle: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Nth Cycle refines physical metal — its product is nickel, cobalt, copper and rare earth output from the OYSTER electro-extraction
    system — and its entire web presence is a 16-page Framer marketing site whose sitemap contains no developer, docs or API
    page; no api./docs./developer./app. subdomain resolves in DNS, and the company GitHub organization publishes zero public
    repositories.
