UC San Diego API Gateway (WSO2 API Manager)
The campus API gateway, running WSO2 API Manager 4.1.0 at api.ucsd.edu on UC San Diego address space (169.228.220.90), with a developer portal, a publisher console and a legacy carbon admin console. The gateway is configured with IsAnonymousModeEnabled=false, so the API catalogue at /api/am/devportal/v2/apis returns 401 to anonymous clients and no list of published APIs is externally observable. This is a gated surface, not an absent one — the settings endpoint answers anonymously and confirms the gateway is live and in service.
