No real discovery documents were found: www.hkex.com.hk and www.hkexgroup.com return 404 for everything, and data.hkex.com.hk returns its SPA HTML shell (a catch-all route) for openid-configuration, oauth-authorization-server and api-catalog while its WAF returns 403 for security.txt, ai-plugin.json and llms.txt. The FINI OAuth server (openam.connect.hkex.com.hk) is not reachable from the public internet, so its ForgeRock OIDC discovery endpoint could not be probed anonymously. hosts: - host: https://www.hkex.com.hk 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://data.hkex.com.hk documents: - path: /.well-known/security.txt status: 403 - path: /.well-known/openid-configuration status: 200 note: SPA HTML shell (catch-all route), not an OIDC discovery document — not saved - path: /.well-known/oauth-authorization-server status: 200 note: SPA HTML shell (catch-all route), not an RFC 8414 document — not saved - path: /.well-known/api-catalog status: 200 note: SPA HTML shell (catch-all route), not an api-catalog — not saved - path: /.well-known/ai-plugin.json status: 403 - host: https://www.hkexgroup.com 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://openam.connect.hkex.com.hk documents: - path: /openam/oauth2/.well-known/openid-configuration status: unreachable note: host not resolvable/reachable from the public internet (participant network only)
