  update:
    x-apievangelist-runtime:
      authentication: HTTP Basic over TLS 1.1+; ERS Admin (read/write) or ERS Operator (read-only) role required
      enablement: API services are disabled by default and must be enabled per node under Administration > System > Settings
        > API Settings
      gateway: Routed through the Cisco ISE API Gateway on port 443; writes reach only the primary PAN
      pagination: page (1-based, default 1) + size (default 20, max 100) on get-all operations
      rate_limit: 100 TPS concurrent ERS API connections; no rate-limit response headers are returned
      idempotency: none — no idempotency key is supported, writes are not safely retryable
      errors: named ERS exception codes, not RFC 9457
      artifacts:
        authentication: authentication/cisco-ise-authentication.yml
        conventions: conventions/cisco-ise-conventions.yml

  update:
    x-apievangelist-note: 'On-premises product: the real base URL is the customer''s own ISE appliance. Where the published
      server names a 10.x/172.x address it is a Cisco lab host and is not callable.'
