generated: '2026-08-28' method: probed source: live probes of every apis.yml baseURL host, the corporate host and the patient-portal host note: >- Two real discovery documents are served, both on the FHIR host and both under the FHIR base path rather than the domain root: the SMART App Launch configuration and an OpenID Connect discovery document. The domain root of the FHIR host answers 503 to every /.well-known/ path (the Epic edge only routes /FhirProxy/*), and www.selectmedical.com answers 403 to every path including paths that do not exist, so nothing there is readable by a machine. The corporate site is behind a WAF that does not discriminate real paths from missing ones — recorded as blocked, not as absent. hosts: - host: epicproxy.et0948.epichosted.com documents: - path: /FhirProxy/api/FHIR/R4/.well-known/smart-configuration status: 200 content_type: application/json; charset=utf-8 file: select-medical-holdings-smart-configuration.json description: SMART App Launch discovery document for the FHIR R4 endpoint. - path: /FhirProxy/oauth2/.well-known/openid-configuration status: 200 content_type: application/json; charset=utf-8 file: select-medical-holdings-openid-configuration.json description: OpenID Connect discovery document for the FhirProxy OAuth 2.0 issuer. - path: /.well-known/security.txt status: 503 - path: /.well-known/openid-configuration status: 503 - path: /.well-known/oauth-authorization-server status: 503 - path: /.well-known/api-catalog status: 503 - path: /.well-known/agent-card.json status: 503 - path: /.well-known/agent.json status: 503 - path: /FhirProxy/api/FHIR/R4/.well-known/oauth-authorization-server status: 404 - path: /FhirProxy/api/FHIR/R4/.well-known/oauth-protected-resource status: 404 - path: /FhirProxy/api/FHIR/DSTU2/.well-known/smart-configuration status: 404 - host: www.selectmedical.com documents: - path: /.well-known/security.txt status: 403 note: WAF challenge; the same 403 body is returned for paths that do not exist. - path: /.well-known/openid-configuration status: 403 - path: /.well-known/oauth-authorization-server status: 403 - path: /.well-known/api-catalog status: 403 - path: /.well-known/ai-plugin.json status: 403 - path: /.well-known/agent-card.json status: 403 - path: /.well-known/agent.json status: 403 - path: /llms.txt status: 403 - host: mychart.selectmedical.com documents: - path: /.well-known/smart-configuration status: 404 - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - path: /llms.txt status: 404 - path: /robots.txt status: 404
