DCP Midstream LLC was a Denver, Colorado-based natural gas gathering, processing, and NGL transportation company that operated as one of the largest U.S. producers and marketers of natural gas liquids. In June 2023, Phillips 66 completed the acquisition of all publicly traded common units of DCP Midstream LP for approximately $3.8 billion, taking its ownership stake to 86.8%. DCP Midstream and Phillips 66 Partners were subsequently merged into Phillips 66's NGL and midstream business; the standalone brand, public filings, developer surface, and corporate website have been retired. The dcpmidstream.com domain no longer resolves to a working site, and there is no public DCP-branded developer portal, API reference, status page, or changelog. This repository documents DCP Midstream as a defunct entity absorbed into the Phillips 66 midstream organization.
DCP Midstream (Acquired by Phillips 66) is profiled on the APIs.io network. Tagged areas include Defunct, Acquired, Phillips 66, Midstream, and Natural Gas.
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/.
