The Domain RDAP Info Retrieval API is an advanced tool designed to provide detailed technical and administrative information about domain names registered on the Internet. When a domain is submitted as input, this API queries the RDAP (Registration Data Access Protocol) and returns a structured response that includes multiple key aspects of the queried domain.
Among the data provided by the API are the domain's statuses, such as whether it is locked against deletion, transfer, or modification. Relevant dates for the domain are also obtained, including its creation, last update, expiration, and recent transfers. Another essential element that is returned is the list of nameservers associated with the domain.
The API also provides details about the registrar, including the name of the entity responsible for the registration, its identifiers, and the contact channels available in case of need (for example, to report abuse). In addition, if the domain is protected by DNSSEC (Domain Name System Security Extensions), the API will include information about the digital signature and the cryptographic algorithms used.
In situations where certain data is not publicly available due to privacy restrictions or data protection regulations, the API clearly indicates that such information has been redacted or limited.
The Domain RDAP Info Retrieval API is ideal for integration into domain monitoring tools, threat analysis systems, digital ownership verification solutions, web infrastructure auditing services, or any application that requires real-time validation of a domain's authenticity and status.
Thanks to its structured JSON format, the API is highly compatible with various development environments and allows for easy implementation in automated workflows. Its robust design ensures a reliable, accurate, and secure experience when accessing critical domain information.
In short, this API allows developers and businesses to obtain a complete and up-to-date view of a domain's status quickly, accurately, and programmatically.
To use this endpoint, you must specify a domain in the parameter.

The RDAP Lookup endpoint returns comprehensive domain information, including registration data, domain statuses, important dates (creation, update, expiration), nameservers, registrar details, and DNSSEC information if applicable.
Key fields in the response include "domainName," "statuses," "created," "updated," "expires," "nameservers," "registrar," and "dnssec," providing a complete overview of the domain's registration and status.
The API returns data in a structured JSON format, organized into key-value pairs. This format ensures easy parsing and integration into various applications, allowing developers to access specific domain information efficiently.
The endpoint provides information on domain registration details, statuses (e.g., locked, active), registrar contact information, nameservers, important dates, and DNSSEC details, offering a comprehensive view of the domain's status.
The response data is organized hierarchically, with main sections for domain details, statuses, registrar information, and nameservers. Each section contains relevant attributes, making it easy to locate specific information.
The data is sourced from the Registration Data Access Protocol (RDAP), which aggregates information from domain registrars and registries, ensuring that the data is accurate and up-to-date.
Typical use cases include domain monitoring, threat analysis, digital ownership verification, web infrastructure audits, and applications requiring real-time domain status validation, enhancing security and operational efficiency.
Users can parse the JSON response to extract specific fields relevant to their needs, such as checking domain availability, monitoring expiration dates, or verifying registrar information for compliance and security purposes.

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.
