The Domain Owner Information Retrieval API allows you to quickly access comprehensive and up-to-date data on any registered domain. When you query a specific domain, the API returns accurate and structured information about its status, ownership, nameserver configuration, DNSSEC support, and much more.
The most relevant data includes the domain name, its extension (e.g., .org, .com, etc.), whether it has DNSSEC enabled, and the associated name servers. It also provides details about the registrar, such as its name, referral URL, contact address, phone number, and abuse email. All of this information is vital for developers, cybersecurity researchers, domain analysts, and brand protection companies.
In addition, the API includes key dates such as the domain creation date, its last update, and the expiration date. The current status of the domain, such as transfer, deletion, or update restrictions, is also reported, allowing you to understand its level of protection.
In summary, the Domain Owner Information Retrieval API is a powerful and efficient tool for obtaining reliable, accurate, and real-time WHOIS information about Internet domains, providing the necessary support for a variety of technical and commercial use cases.
To use this endpoint, you must specify a domain in the parameter.

The API returns detailed WHOIS information for a specified domain, including ownership details, registrar information, DNSSEC status, nameservers, key dates (creation, update, expiration), and the current status of the domain.
Key fields in the response include domain name, registrar name, contact details, DNSSEC status, nameservers, creation date, last updated date, expiration date, and domain status (e.g., active, locked).
The response data is structured in a JSON format, with clear key-value pairs for each piece of information, allowing easy parsing and integration into applications.
The API provides information on domain ownership, registrar details, DNSSEC support, nameserver configurations, key dates, and the current status of the domain, making it comprehensive for domain analysis.
Users can customize requests by specifying the domain name in the query parameter, allowing targeted retrieval of WHOIS information for any registered domain.
The data is sourced from WHOIS databases maintained by registrars and domain registries, ensuring that the information is accurate and up-to-date.
Typical use cases include cybersecurity research, domain ownership verification, brand protection analysis, and monitoring domain status for potential threats or changes.
If the API returns partial or empty results, it may indicate that the domain is unregistered or that WHOIS privacy settings are in place. Users should verify the domain's registration status through other means if necessary.
To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
