Terms of use
Last updated 23 July 2026.
By using this free domain checker you agree to the terms below. They are intentionally short.
What the service is
A free tool that reports a domain's TLS certificate, registration and DNS status. It is offered as a convenience, on an "as is" and "as available" basis, with no uptime or availability guarantee.
Acceptable use
- Check domains you own or have a legitimate reason to inspect.
- Do not use the tool to probe private, internal, or loopback hosts — such addresses are refused on purpose.
- Do not attempt to bypass the daily free limit, overwhelm the service, or use it to attack third parties.
- Automated or high-volume use belongs on the API, not this page.
Accuracy
Results come from live handshakes, registry (RDAP) responses and public DNS. Registries may redact, rate-limit, or delay data, so a blank field means "not published", not "does not exist". Nothing here is a guarantee of a domain's security, availability, or ownership. Do not rely on it as your only monitoring.
Limitation of liability
To the maximum extent permitted by law, the service is provided without warranties of any kind, and we are not liable for any loss arising from use of, or reliance on, its results — including missed renewals or outages.
The paid API
Paid tiers are sold and billed through RapidAPI and are additionally governed by RapidAPI's terms. See the API listing for details.
Changes
These terms may change as the tool evolves. Continued use after a change means you accept the updated terms.
