Associated Domain Finder API

API Structure

The Associated Domain Finder API allows you to reveal all associated domain names of a specific domain within seconds. By querying this API, all domains with similar records such as Whois, DNS, and IP address will be mapped, so you can quickly discover domain associations.

Domains have many relationships with others. These associations relate to WHOIS, DNS, and SSL records and can be seen in the table below. With each association query parameter given in the table, associated ones can be returned for a specific domain name. You can enter multiple parameters separated by commas.

Let's start by creating a two-week free account from Deepinfo Platform, get your API key, and you are ready. Next, you can test using the following cURL command.

Sample with the curl command:

curl --request GET \
  --url https://api.deepinfo.com/v1/discovery/associated-domain-finder?domain=dofo.com&page=1&strict=yes&include_subdomains=yes&association=whois_registrant_email,whois_registrant_phone,dns_ns,dns_mx,whois_registrant_phone_normalized,whois_registrant_email_apex_normalized,whois_registrant_organization,whois_ns,ssl_subject_organization,whois_registrant_organization_normalized,dns_a \
  --header 'Accept: application/json' \
