generated: '2026-09-12' method: probed source: live GET of the named /.well-known/ path list on every host this record knows note: Five real documents were served, all of them OAuth/OIDC discovery, and all of them on the API and auth hosts rather than the marketing domain. agentsmyth.com and www.agentsmyth.com serve a Next.js 404 for every probed path. app.agentsmyth.com is a WorkOS AuthKit single-page app that answers HTTP 200 with an HTML shell for EVERY /.well-known/* path including agent-card.json - that is a catch-all, not a document, and it is recorded as a miss. No security.txt, no api-catalog, no ai-plugin.json and no A2A agent card is served anywhere. hosts: - host: agentsmyth.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 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - path: /.well-known/aauth-resource.json status: 404 - host: www.agentsmyth.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 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: api.agentsmyth.com documents: - path: /.well-known/oauth-authorization-server status: 200 file: agentsmyth-api-oauth-authorization-server.json note: Served as a 302 to the same document on app.auth.agentsmyth.com; the saved body is the followed result. - path: /.well-known/oauth-protected-resource/mcp status: 200 file: agentsmyth-oauth-protected-resource-mcp.json note: RFC 9728 protected-resource metadata for the MCP endpoint.
