generated: '2026-07-27' method: searched source: live probes of every Alinta Energy and CDR host on 2026-07-27 note: > The standard /.well-known/ discovery surface was probed on every host in apis.yml (Alinta's own CDR public base URI, the AER-hosted Energy Made Easy CDR host that serves Alinta's generic plan data, and the Alinta corporate web estate). Nothing is published. Alinta's own CDR host answers 404 for every /.well-known/ path, and the corporate site answers 403 to all automated clients (site-wide WAF), so a 403 is NOT evidence that a document exists. No anonymous OpenID Connect discovery document is served: under the Consumer Data Standards a data holder's infosec base URI (and therefore its /.well-known/openid-configuration) is disclosed only through the CDR Register's authenticated data holder brand DETAIL endpoint, which requires an ACCC-accredited client certificate. In place of /.well-known/, the machine-readable operational discovery surface Alinta DOES serve is the CDR Common Discovery pair — /cds-au/v1/discovery/status and /cds-au/v1/discovery/outages — both confirmed HTTP 200 (see lifecycle/alinta-energy-lifecycle.yml). hosts: - host: https://public.cdr.alintaenergy.com.au role: Alinta-operated CDR public base URI (from the CDR Register) documents: - {path: /.well-known/security.txt, status: 404} - {path: /.well-known/openid-configuration, status: 404} - {path: /.well-known/oauth-authorization-server, status: 404} - {path: /.well-known/api-catalog, status: 404} - {path: /.well-known/ai-plugin.json, status: 404} - host: https://cdr.energymadeeasy.gov.au role: AER Energy Made Easy CDR platform (hosts Alinta's generic plan data) documents: - {path: /.well-known/security.txt, status: 404} - {path: /.well-known/openid-configuration, status: 404} - {path: /.well-known/oauth-authorization-server, status: 404} - {path: /.well-known/api-catalog, status: 404} - host: https://www.energymadeeasy.gov.au role: AER Energy Made Easy consumer site documents: - {path: /.well-known/security.txt, status: 404} - host: https://www.alintaenergy.com.au role: Alinta corporate site (site-wide WAF returns 403 to automated clients) documents: - {path: /.well-known/security.txt, status: 403} - {path: /.well-known/openid-configuration, status: 403} - {path: /llms.txt, status: 403} security_txt: none openid_configuration: none (gated behind CDR Register accreditation)
