6K
6K Inc is a North Andover, Massachusetts advanced-materials company that produces engineered powders and battery materials with UniMelt, its patented microwave-based production-scale plasma system. Named for the roughly 6,000 K plasma temperature it operates at — the temperature of the surface of the sun — UniMelt uses tightly controlled thermal plasma beams to melt or vaporize precursor feedstock into particles with precise size distribution and crystalline phase, in seconds rather than the days conventional processes require, while cutting energy use and eliminating wastewater. The company operates through two divisions. 6K Additive, with production in Burgettstown, Pennsylvania, makes sustainably sourced metal powders for additive manufacturing — titanium Ti-6Al-4V, nickel superalloys Ni625 and Ni718, stainless SS316L, refractory tungsten, niobium C103, copper C18150 and the HEA1000 refractory alloy — reclaiming CNC scrap and revert metal into premium AM powder. 6K Energy produces domestically sourced lithium-ion battery cathode and solid-state materials including NMC, LFP, LLZO, LMO, LTO and LNMO. Additional applications span semiconductor CMP, specialty ceramics, advanced coatings, lighting and display materials, nano-engineered powders, and federal/defense programs; 6K has received US Department of Defense and Department of Energy awards for domestic critical-materials capacity. 6K is a privately held company whose shares trade on secondary markets. Enrichment probing on 2026-07-31 found no public developer API, OpenAPI/AsyncAPI/GraphQL contract, developer portal, SDK, MCP server, agent card, or event surface — 6K is a materials manufacturer, not an API provider.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles 6K the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — 6K scores 9.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile 6K
Each block below is one kind of artifact we hold for 6K. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

The organization behind the API

This is an independent, third-party profile of 6K, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
