The only authenticated surface on any PanTheryx-controlled host is the Shopify customer account OAuth 2.0 / OpenID Connect provider that fronts the two brand storefronts. Agent discovery on those storefronts is fully anonymous: tools/list, the UCP merchant profile, the catalog JSON endpoints and llms.txt all answer with no token. anonymous_surface: - surface: MCP tools/list endpoints: - https://relesium.com/api/ucp/mcp - https://www.lifesfirstnaturals.com/api/ucp/mcp credential_required: false observed_status: 200 - surface: UCP merchant profile endpoints: - https://relesium.com/.well-known/ucp - https://www.lifesfirstnaturals.com/.well-known/ucp credential_required: false observed_status: 200 schemes: - id: shopify_customer_account_oidc type: openIdConnect applies_to: relesium.com issuer: https://shopify.com/authentication/60191506528 authorization_endpoint: https://account.relesium.com/authentication/oauth/authorize token_endpoint: https://account.relesium.com/authentication/oauth/token jwks_uri: https://account.relesium.com/authentication/.well-known/jwks.json end_session_endpoint: https://account.relesium.com/authentication/logout response_types_supported: - code token_endpoint_auth_methods_supported: - client_secret_basic - client_secret_post id_token_signing_alg_values_supported: - RS256 discovery: - /.well-known/openid-configuration - /.well-known/oauth-authorization-server - /.well-known/oauth-protected-resource note: >- A customer-account identity provider, not a partner/developer API program.
