Domain Search Examples · Example 21 of 24 in Filters › WHOIS

First Registered Before 2001

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

Field: domain.whois_create_date_historical
Operator: lte

Matches records whose domain.whois_create_date_historical is on or before 2000-12-31 (2000-12-31T23:59:59Z).

whois_create_date_historical keeps every creation date seen for the domain, so this also finds domains that were registered before 2001 and later re-registered.

In the response, look at results[].domain.whois_create_date_historical.
