Domain Search Examples · Example 8 of 9 in Filters › Subdomain

Root Subdomain Label

POSThttps://api.deepinfo.com/v1/discovery/domain-search

Field: subdomain_root
Operator: eq

Matches records whose subdomain_root equals www.

For a one-label subdomain such as www.acme.example, subdomain, subdomain_last and subdomain_root are all www; they differ on deeper subdomains.

In the response, look at results[].subdomain_root.punycode.
