# Including Subdomains Adds the subdomains of the matching domains: 20 records instead of 8, such as www.bikingsupplies.us. Source: https://docs.deepinfo.com/reference/discovery/reverse-whois-email/examples/include-subdomains/ Last updated: 2026-09-24 --- `GET https://api.deepinfo.com/v1/discovery/reverse-email?email=support%40godaddy.com&include_subdomains=true&page_size=25` Adds the subdomains of the matching domains: 20 records instead of 8, such as www.bikingsupplies.us. Example 2 of 2 in **Options** · [Reverse WHOIS Email Examples](/reference/discovery/reverse-whois-email/examples/) · endpoint: [Reverse WHOIS Email](/reference/discovery/reverse-whois-email/) Tags: `param` `include_subdomains` · `param` `email` · `value` `true` · `value` `support@godaddy.com` By default the API returns registrable domains only (`type: 1`). `include_subdomains=true` adds their subdomains (`type: 2`), which carry the WHOIS record of their domain. The total grows from 8 to 20. The records shown include `www.bikingsupplies.us` and `www.rucksacksupplies.us`, both with `type: 2`. In the response, look at `results[].type` and `results[].punycode`. ## Request | Parameter | In | Value | |---|---|---| | `email` | query | `support@godaddy.com` | | `include_subdomains` | query | `true` | | `page_size` | query | `25` | ```bash curl 'https://api.deepinfo.com/v1/discovery/reverse-email?email=support%40godaddy.com&include_subdomains=true&page_size=25' \ -H 'apikey: YOUR_API_KEY'
