Our system gives you access to over 550 TLDs. A growing number of direct accreditations and memberships, as well as our ambition to constantly optimise the system, have resulted in one of the most sophisticated registration systems. Thanks to the standardised interfaces for all TLDs, as a domain reseller you can regularly expand your portfolio without further effort.

CPS-Datensysteme GmbH is an official member of DENIC eG
With a personal contact person and direct technical support, we also help you as a registrar to realise demanding projects.
Automation
The registration system is fully automated and processes all orders without delay. All TLDs are managed through a standardised interface and asynchronous messages (expire, policy hold) from the registries are available for polling – or can optionally be sent by e-mail.
API and web interface
An XML-POST-API, an e-mail robot (XML-SMTP) and of course a comprehensive web interface with many functions – such as bulk orders – is at your disposal.
Accreditations
We maintain 98% direct accreditations, giving you technical direct access to the registries without any intermediaries. This reduces the risk of interface downtimes and significantly speeds up and simplifies order processing.

DNSSEC
The Domain Name System Security Extensions (DNSSEC) ensure the authenticity of DNS transactions and prevent attacks such as cache poisoning. Cache poisoning can be used by criminals to direct website requests to external servers. This technique is therefore used in preparation for so-called phishing, which is used to read access data and other personal information. Since December 2011, you have had the option of depositing the key material for using DNSSEC with selected registrars via our registration system.
WHOIS proxy
Most registries require the owner’s data to be submitted to register a domain in order to store it in a WHOIS database. The data submitted is usually name, address, e-mail, telephone and fax number. Incorrect information can lead to the suspension or even cancellation of a domain. These stored data can be viewed by anyone via a public WHOIS query. The WHOIS proxy service of CPS-Datensysteme GmbH anonymises this data. This effectively prevents the misuse of data for spam, harassment or identity theft. The domain owner can still be contacted despite the anonymisation: It is possible to contact the current domain holder at any time by e-mail via the page www.whoisprivacy.one. Our WHOIS proxy service is fully compliant with the ICANN guidelines.
Global RDAP service
This product gives you access to our Global RDAP (Registration Data Access Protocol) server. The server provides availability information (partly including registration data) for individual domains, provided they belong to a TLD offered by CPS-Datensysteme. The use of the service is 100% RFC-compliant and covers gTLDs such as .COM, .NET or .ORG, as well as a large number of ccTLDs. In proxy mode, we merge structured RDAP data and WHOIS data in text form into a JSON response – depending on which technology is supported by the requested registrar. We also offer you a quick availability query in check mode. In addition to RDAP and WHOIS, the DNS is also used here. Each check request is also checked against an extensive database of premium domains and hits are marked accordingly in the output.
Trademark Clearinghouse (TMCH)
The Trademark Clearinghouse (TMCH) ensures the protection of trademarks when assigning the new gTLDs(nTLDs). If a trade mark is registered in the TMCH, trade mark owners have the opportunity to participate in the “Sunrise Phase”. In this phase, trade mark owners are given priority when registering domains. This is followed by the general domain allocation phase, during which the “Trademark Claims Service” is initially provided for a period of 90 days. This is a TMCH notification service that warns trademark owners and domain holders of possible infringements in the event of domain registrations.
