Whois API Documentation

Overview

  • Live Whois Lookup
    Live Whois Lookup provides real-time whois domain data.
  • Historical Whois API
    Whois history API helps to get historical domain whois records.
  • Reverse Whois API
    Reverse whois lookup API lets you get whois records by keyword, email, registrant name or company.
  • Bulk Domain Lookup
    Bulk domain whois lookup allows you to query multiple domains in one request. You can do bulk Whois search through an API upto 100 domains in JSON / XML formats in single request. If you want to query bulk whois upto 3M, you are required to upload files via our billing portal. We'll send you an email with a link to download your whois file as soon as crawling completes.

Authorization

You can make authorized requests to our API by passing API key as a query parameter. To get your API key, login to our billing dashboard and get your API key! If your API key has been compromised, you can change it by clicking on reset button in billing dashboard.

Response

Live Whois API provides response in JSON/XML formats. You can pass format as parameter to consume API in your required format. Default format is JSON. ICANN grant authority to registrant to put WHOIS GUARD which will hide their personal information like name, email etc. In that case you will get REDACTED FOR PRIVACY or some text like this. Different registrars put different text for WHOIS GUARD. We crawl data as ICANN registry provide us. In some cases, registrar / registrant show limited information, you will observe missing fields in our response in that case. Following is the complete Whois data response format.
