Registrar list vs. full WHOIS export — what's the difference?

For Nicline, both options cover the same 414,800 active domains registered through this registrar.
The basic file is a single-column list of domain names (one per line). The detailed WHOIS export adds registrar metadata and enrichment: registration and expiry dates, Majestic rank, server IP and country, plus emails and phone numbers when we find them on the site.
Column definitions and file layout are described in our FAQ on dataset formats.

Can I schedule automatic downloads for this registrar?

Yes. The WHOIS Registrars API lets you pull the basic list or the full export for registrar_id=379 on a cron or pipeline — no manual browser download required. See the registrar API section for parameters and examples.

Are emails and phones present for every domain in the WHOIS export?

No. Contact fields are optional enrichments: we crawl public pages linked to each domain and store what we find. Coverage varies by site; many domains have no published email or phone.
Do not use these fields for bulk or unsolicited messaging. They are intended for filtered, compliant research and outreach only.
