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.

Nth Cycle is profiled on the APIs.io network. Tagged areas include Company, Critical Minerals, Mining, Recycling, and Battery Materials.

Nth Cycle’s developer surface includes engineering blog, support, YouTube channel, and 8 more developer resources.

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.

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.

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/.

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

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

13 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 0.0 — up to +25.0 composite points
Developer Ergonomics scores 7.1 — up to +18.6 composite points
Access Clarity scores 21.1 — up to +15.8 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/nth-cycle/apis.yml: open an issue on github.com/api-evangelist/nth-cycle 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.

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.

  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.
