Description

Check a domain's registration date and calculate its age.

How to Use

1

1. Pass the domain in the `domain` parameter. 2. Check `age_years` for the domain's age and `is_new` to flag recently registered domains.

About This Tool

Domain Age Checker looks up a domain's registration date via RDAP and calculates its age in days and years. It returns registrar info and flags newly registered domains (less than 30 days old) — a common signal for phishing and spam detection.

Why Use This Tool

Phishing detection — Flag newly registered domains as potential threats
Brand protection — Monitor when copycat domains were registered
Trust scoring — Use domain age as a signal in fraud detection systems
Due diligence — Verify how long a business domain has been registered

Frequently Asked Questions

What counts as a "new" domain?

Any domain registered less than 30 days ago is flagged with `is_new: true`.

What if the domain isn't registered?

The response returns `registered: false` with null age fields.
