description: 'CenturyLink is the residential broadband and home services brand of Lumen Technologies, a Fortune 500 telecommunications
  provider operating one of the largest fiber networks in North America. Following the Level 3 acquisition and rebrand to
  Lumen, CenturyLink''s developer surface is exposed through the Lumen Developer Center, which publishes REST APIs secured
  by OAuth 2.0 for enterprise location qualification, quote-to-order, provisioning, billing, notifications, CDN and edge compute,
  DDoS mitigation, and Public Sector networking products. The production API gateway answers at api.lumen.com, but no OpenAPI,
  AsyncAPI or GraphQL contract is published anonymously: the Developer Center is a module-federation single-page app that
  returns the same HTML shell for every path and loads its specifications from a sign-in-gated service.'

  description: 'The Lumen Developer Center publishes Lumen''s enterprise API catalog, including Location, Quoting, Ordering,
    Service Inventory, Billing, Outbound Notification, and Trouble Ticket APIs. All APIs use OAuth 2.0 Client Credentials
    against api.lumen.com and require registration for API access plus administrator enablement of the API products an API
    key covers. Base URL confirmed by live probe on 2026-09-05: the token endpoints https://api.lumen.com/oauth/v1/token and
    /oauth/v2/token both answer with real OAuth errors. The v2 gateway identifies itself as Apigee. The former /apis index
    at developer.lumen.com now 302s to the site root; the shipped SPA route table declares only /devcenter/home, /devcenter/getting-started,
    /devcenter/support, /devcenter/overview and /devcenter/docs/:category/:section?/:slug?.'

  description: The Lumen API Marketplace was the enterprise catalog where partners and customers browsed APIs and requested
    credentials. It has been folded into the Lumen Developer Center and Lumen Connect. As of 2026-09-05 the apimarketplace.lumen.com
    host still answers, but it presents a TLS certificate for CN=developer.centurylink.com that expired 2026-01-15, so an
    ordinary browser refuses the connection before its 301 to developer.lumen.com is ever followed. Its two former pointers
    have been removed from this record and the finding is captured in lifecycle/centurylink-lifecycle.yml. API key creation,
    editing, product scoping and client-secret reset now live in Lumen Connect and are documented on docs.lumen.com.

    former pointers were dead and have been removed. The surviving public documentation for API access to the successor products
    is the Lumen Connect APIs section on docs.lumen.com. No OpenAPI document from this family is published at any reachable
    URL.'

    previously carried here were dead as of 2026-09-05 — blog.centurylink.com no longer resolves in DNS and /en-us/solutions/public-sector.html
    returns 404 — and have been replaced with the live public-sector section.
