Exceptionally robust whois parser that parses a variety of freeform whois data into well-structured fields(in XML and JSON) that your application can read.
-
The intelligent parser we deploy is very fault tolerant, for example, it is able to parse out the name, organization, street, city, state/province,
postal code, phone number, and fax from a freeform human-written contact address. See the example data capture below. Or try the whois look demo above.
-
Parsing support for all whois registrars, constantly tested and improved
-
Strips out header and footer text for a clean display of the whois data
-
Works over basic HTTP, thus avoiding firewall-related problems of accessing Whois servers on port 43
-
Returns an indication of whether a domain is available
Alternatively, you may host your own WhoisAPI webservice in house by purchasing a software license
