The company was acquired by ConocoPhillips in 2024, and its public web presence now redirects to ConocoPhillips. No public developer APIs have been identified.
Marathon Oil is profiled on the APIs.io network. Tagged areas include Energy, Exploration, Natural Gas, Oil, and Production.
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/.
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 github.com/api-evangelist/marathon-oil: open an issue to ask a question, or submit a pull request to add artifacts.

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/.'
