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/. This rating is computed from github.com/api-evangelist/usa-rare-earth: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?

  detail: 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.
