USA Rare Earth
USA Rare Earth, Inc. (Nasdaq: USAR) is an American critical-minerals and advanced-materials company building a domestic mine-to-magnet rare earth supply chain. It operates a 310,000 sq. ft. sintered neodymium-iron-boron (NdFeB) permanent magnet manufacturing facility in Stillwater, Oklahoma, and holds the Round Top heavy rare earth and critical minerals deposit in Hudspeth County, West Texas. The company produces rare earth elements, oxides, metals and sintered permanent magnets for defense, automotive, robotics, industrial and clean-energy customers, with the stated aim of reducing U.S. dependence on offshore rare earth processing and magnet production. It is a materials producer and manufacturer, not a software or data company, and publishes no public developer program, API, or machine-readable interface.
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 USA Rare Earth 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 — USA Rare Earth scores 10.7/100 (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.
Why this profile is thin
USA Rare Earth makes physical goods — sintered NdFeB magnets and rare earth oxides/metals — and www.usare.com is a WordPress marketing site whose only machine-readable endpoint is the /wp-json index; every spec and /.well-known/ path 404s and the site's own WordPress REST content routes answer 401 rest_forbidden, so there is no developer surface to profile.
This is an honest zero, not a gap in our research. USA Rare Earth does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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.

This is an independent, third-party profile of USA Rare Earth, 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.
