FedNow API authentication is Client ID + PKI certificate over the credential-gated FedLine Developer platform, not an anonymous OAuth/OIDC surface, so there is no anonymous authorization-server or OIDC discovery document to fetch. Empty result is expected and valid for a gated financial-institution rail. hosts: - host: https://www.frbservices.org 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 x-shape-fix: converted: '2026-08-20' from: documents note: Rewritten into hosts[] -> documents[], the only shape well_known_docs() in score.rb reads.
