Response

Returns a hash map containing domain name availability status for the requested TLDs:

  • Domain Availability Status (status)

    • available - domain name available for registration

    • regthroughus - domain name currently registered through the Registrar whose connection is being used to check the availability of the domain name

    • regthroughothers - domain name currently registered through a Registrar other than the one whose connection is being used to check the availability of the domain name. If you wish to manage such a domain name through your Reseller / Registrar Account, you may pass a Domain Transfer API call. 2

    • unknown - returned, if for some reason, the Registry connections are not available. You should ideally re-check the domain name availability after some time.

      Note
      • In case of Donuts TLDs, domain name availability can be checked for a maximum of 5 domain names per Donuts TLD group in one API call. Including more than 5 domain names belonging to the same Donuts TLD group in an API call will return the status as unknown for all the domain names.
