Check for availability

To find out whether a domain is still available or not, you can send the following request to our server. If you specify multiple domains, do not forget to increase the timeout value of your scripts as it may take a couple of seconds before our server will return an answer.

Please note that this service is not available for all top level domains and that the number of daily requests is limited. This limitiation is necessary due to the fact that most of the registries limit the number of allowed requests and blacklist IP addresses exceeding this limit.

You can find the number of allowed request in the section Your profile > Allowed requests.

XML Template
<?xml version="1.0" encoding="UTF-8"?>
<request xmlns:domain="">

<domain:check> (Occurences: 1)
<domain:name> (Occurences: 1+)
Note: Repeat this section to check multiple domains in one request
R #DOMAIN.TLD# Name of the domain to check for availability

If the action was succesful, the following code will be returned:
<?xml version="1.0" encoding="UTF-8"?>
<response xmlns:domain="">
    <result code="1000">
        <msg>Command completed successfully</msg>
