Level 3 Communications was a multinational telecommunications and Internet service provider that operated one of the largest fiber networks in the world, delivering Tier-1 IP transit, managed services, and content delivery. In 2017 it was acquired by CenturyLink, which later rebranded the combined company as Lumen Technologies. No public API program is documented under the legacy Level 3 brand.
Level 3 Communications is profiled on the APIs.io network. Tagged areas include Telecommunications, Internet Service Provider, Fiber, Networking, and Historical.
Regulatory Posture applies to this provider. Its tags matched the
Telecommunications 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/.
