    Function Invoke-APIOnypheASDDnsDomainNsExist {
    <#
      .SYNOPSIS
      create input for Invoke-OnypheAPIV2 function and then call it to query the ASD Dns Domain Ns Exist APIv1

      .DESCRIPTION
      create input for Invoke-OnypheAPIV2 function and then call it to query the ASD Dns Domain Ns Exist
      APIv1 - checks whether the given domain(s) have an existing NS record (a live DNS lookup), returning
      {"domain":"...","exist":"true"|"false"} per domain. Live-tested 2026-09-19: "onyphe.io",
      "microsoft.com", "sovcloud-core.fr" and "sovcloud-api.fr" all returned "exist":"true"; a deliberately
      made-up domain ("doesnotexist-abc123xyz.io") returned "exist":"false" - confirms the endpoint performs
      a real live check rather than always returning true. Same bare "domain"-array request body as
      Invoke-APIOnypheASDDnsDomainExist. Like that sibling endpoint, Onyphe does not document
      -IncludePattern/-ExcludePattern/-Untrusted for this one either, so they are not exposed here. BETA
      endpoint, requires a Griffin View or Griffin View ASM Edition subscription with a non-commercial use
      licence (see Get-OnypheUserInfo's asd.stdapis property).

      .PARAMETER Domain
      -Domain string[]
      one or more domains to query

      .PARAMETER AsLines
      -AsLines switch
      render results as one JSON object per line instead of with context (server default is with context)

      .PARAMETER APIKEY
      -APIKey string{APIKEY}
      Set APIKEY as global variable

      .PARAMETER FuncInput
      -FuncInput hashtable
      original bound parameters of the calling wrapper, threaded through to the result object's cli-func_input property

      .OUTPUTS
      TypeName: PSOnyphe
