FAQ

How does this domain checker work?

This tool queries the Frostbyte Domains API to check domain availability across 18 TLDs simultaneously. Results are returned in real-time from authoritative DNS registries.

Is this free to use?

Yes. The web tool is completely free with no limits. If you want to automate domain checks via API, you get 200 free credits when you create an API key (no signup required).

Can I register domains through this tool?

Not directly through this page, but you can register domains via the Frostbyte Domains API. See the Domain Registration API guide for details.

How accurate are the results?

Results are queried in real-time from domain registries. Availability is accurate at the time of the check, though high-demand domains can be registered by others between checking and registration.

Can I use the API to check domains programmatically?

Yes. The API documentation includes endpoints for domain search, TLD listing, and registration. Get a free API key with a single POST request.
