## What can I do with WhoisXML through looot?

The jobs on this page: whois record for a domain, dns records for a domain, subdomains of a domain, check if a domain is available, locate an ip address, verify an email address. The page marks any job whose endpoints are not in the live catalog.

## What does WhoisXML cost through looot?

You pay per call. The price of each endpoint is shown before you run it, so your agent can check it first and pick the cheapest one that fits.

## Do I need a WhoisXML account to use it through looot?

You connect to looot, not to WhoisXML. looot makes the provider call for you and bills each call at the price shown before the run.

## How does my agent find the right WhoisXML endpoint?

It searches the looot catalog for the task, reads the endpoint's parameters and price, and then calls it. You do not have to read WhoisXML's docs first.

## What can I use with WhoisXML in looot?

Providers that often go with WhoisXML are BuiltWith, DataForSEO, Context.dev, ZeroBounce. All of them sit behind the same looot MCP connection.

## Can I try a WhoisXML lookup without an agent?

Yes. The free WHOIS lookup at /free-tools/whois-lookup and the domain availability checker at /free-tools/domain-availability-checker run the same WhoisXML endpoints in your browser. Use the MCP connection when your agent needs many lookups or wants to act on the answer.

## What can the WhoisXML API not do through looot?

Many WHOIS records are redacted for privacy, so the owner's name and email are often hidden; the registrar and dates usually remain. The catalog does not run WhoisXML's historical WHOIS or reverse WHOIS search today, and an IP lookup gives a network location, not a street address.
