source: live probes of the LexisNexis Risk Solutions web + developer-portal hosts
note: >-
  LexisNexis Risk Solutions publishes no /.well-known/ discovery surface on its own hosts.
  The only document found is the RFC 9116 security.txt served on the parent registrable
  domain lexisnexis.com, which is the registrable domain of risk.lexisnexis.com and therefore
  covers the Risk Solutions web property. Every /.well-known/ path probed on
  developer.lexisnexisrisk.com returned 404 and every path on risk.lexisnexis.com returned
  403 or 404. No OIDC or OAuth authorization-server metadata is published anonymously; the
  developer portal is a SwaggerHub Portal instance whose product routes redirect an
  unauthenticated client to /sp-portal/session-expired.
