The API surface behind the Klarys tenant application at klarys.app. Klarys markets API and EDI integration with customer ERP, accounting and product-reference systems, and the application serves an anonymous RFC 8414 OAuth 2.0 authorization-server metadata document at https://klarys.app/.well-known/oauth-authorization-server (issuer https://klarys.app/api/public/o) with authorization_code, client_credentials and refresh_token grants, PKCE S256, dynamic client registration, token revocation and introspection. No public API reference, OpenAPI document or developer portal was found: the schema endpoint at https://klarys.app/api/schema/ returns HTTP 401 {"code":1003,"error":"User is unauthenticated"}, so the contract is customer-gated.
