Interactive intelligence tool
Run the check, then ship the workflow
Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.
Review decision-ready signals
Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.
Automate the workflow that works
Use the request and response examples to turn a one-off check into an API call or recipe.

What this tool helps you decide
Each page is shaped around a practical operational question, not just a raw lookup.
See the current DNS, registration, security, pricing, or reputation evidence.
Compare the result with related checks so the next move is easier to trust.
Copy examples, open linked tools, or move into API documentation when you need scale.
Trust signals before you integrate
Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.

Frequently asked questions
Do I need an x-default entry?
It is recommended. x-default tells search engines which page to show when no language or region matches the visitor.
Should a page list itself in its hreflang tags?
Yes. Each page should include a self-referencing entry along with every alternate version.
How many alternates are checked?
Up to 10 by default and up to 20 through the API. Alternates that cannot be read are reported as unknown.
