Who Uses the WHOIS API

Cybersecurity Platforms

Enrich alerts with registrant data. Correlate malicious domains back to threat actors via registrar, nameserver, or registrant patterns.

Legal & Brand Protection

Download daily WHOIS database files and scan for newly registered lookalike domains. Identify brand infringement early before it escalates.

SaaS & Platform Tools

Integrate WHOIS database downloads into your product to enrich domain data records at scale inside your platform.

Domain Research Tools

Power your domain intelligence, expiry tracking, or registrant analysis tools with structured daily WHOIS database files.

Compliance & Due Diligence

Domain Expiry Monitoring

Download WHOIS databases on a schedule and parse expiry dates across your domain watchlist. Alert your team before valuable domains lapse.

Prefer manual downloads?

Download the same WHOIS database from your client dashboard

The API and the manual download both deliver the same ZIP file. The API automates it - schedule a cron job and never log in again. The client dashboard is available if you prefer manual control.
