Kyo Attain Platform API
The Attain platform API is the backend serving the Kyo Care portal (portal.kyocare.com) and the Kyo Care mobile app. It is an OAuth 2.0 / OpenID Connect protected API fronted by AWS Cognito, publishing live /.well-known/openid-configuration and /.well-known/oauth-authorization-server discovery documents that advertise authorization_code (with PKCE S256) and client_credentials grants. No public OpenAPI, documentation or open registration is offered — access is limited to Kyo's own first-party clients.
