How do you perform a search using "company" parameter on whois data in reverse API?
The company parameter enables you to search for domain whois data based on a publicly available company name. Simply input the company name, and the API will return domains associated with that company using search based query.

How do you perform a search using "owner" parameter on whois data in reverse API?
With the owner parameter, you can search for domain whois data based on the name of the domain owner that will be publicly available in records. Enter the owner's name, and the API will provide a list of domains linked to that owner using search based query. For example, if you enter "michael", the API will search that name in full name of the owner.
What is the "exact" match parameter in reverse WHOIS?
The "exact match" parameter is an optional feature in reverse WHOIS searches. When used with keywords, company names, or owner names, it ensures that the search results match the exact terms entered. This helps users find more precise and relevant information by filtering out results that don't perfectly align with the query.

Note: The "exact match" parameter can only be used with keywords, owner/registrant names, or company names. It is not applicable for email addresses, meaning you cannot use exact match to filter results based on email addresses.
Can I perform a search on whois records based on email address in reverse API?
Yes, you can search for whois information using an email address. The email parameter allows you to retrieve domains associated with a specific email address. Please note that this search is limited to publicly available email addresses. The search is precise, so make sure to input the complete and exact email.
How can I perform a regex-based search for email addresses in reverse WHOIS?

To search for email addresses using regex in reverse WHOIS, use the 'email' parameter with regex patterns. The 'email' parameter supports:

  • Exact match: Allows you to search for specific email addresses exactly as entered, such as [email protected] or [email protected]. This will return results that match these email addresses precisely.
  • Regex match: Enables more flexible searches using patterns to match a range of email addresses. For example, g***@outlook.com can match addresses like [email protected], and q*.l*@gmail.com can match addresses such as [email protected] or [email protected]. This approach accommodates variations within the specified pattern.

Note: Regex matching is only available for email addresses. For keywords, owner/registrant names, or company names, use the optional parameter exact set to 'false', or omit it as it defaults to 'false'.

What are the length limitations for the keyword parameter in reverse whois API queries?
When using the keyword parameter in reverse whois API queries, the keyword should be a minimum of 3 letters and a maximum of 63 letters.
