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/.

x-status-note: 'ConocoPhillips completed its $22.5B acquisition of Marathon Oil on 2024-11-22 (announced 2024-05-29, stockholder
  approval 2024-08-29). Marathon Oil no longer hires as a distinct entity — its roles are posted on ConocoPhillips'' board
  — so a job corpus filed under this slug is ConocoPhillips'' demand, not Marathon Oil''s. Kept as a tracked entity with the
  relationship recorded rather than deleted: the company existed and its history is real. NOT to be confused with Marathon
  Petroleum (MPC), a separate company that spun this one out in 2011 and is tracked at all/marathon-petroleum/.'
