dns - Service to validate if url has valid toplevel domain -

i'm seraching service can validate if given url has valid toplevel domain. since list of topleveldomain expanding using txt file not soltion anymore, want utilize webservice preferable iana.org.. using txt file doesn't country-code top-level domains "co.at" etc...

the best thing have found far list of toplevel domains from, isn't stated when gets updated. (link: http://data.iana.org/tld/tlds-alpha-by-domain.txt)

while can't feed straight urls, obvious service utilize check valid top-level domains dns itself. send query 1 of root servers , see if rcode noerror or nxdomain.
