The Domain RDAP Lookup API allows you to query any domain using the RDAP protocol, the modern replacement for WHOIS. Retrieve essential domain information such as registrar details, creation and expiration dates, name servers, and current status in a convenient JSON format. Ideal for checking domain availability and monitoring changes.
The Domain RDAP Lookup API returns essential domain information, including registrar details, creation and expiration dates, name servers, and the current status of the domain in a JSON format.
Key fields in the response include "domain," "registered," "registrar," "creationDate," "expirationDate," "updatedDate," "status," and "nameServers," providing a comprehensive overview of the domain's registration details.
The response data is structured in JSON format, with key-value pairs representing domain attributes. For example, "status" is an array listing restrictions, while "nameServers" contains the DNS servers associated with the domain.
The API provides information such as whether the domain is registered, registrar name, registration dates, domain status, and associated name servers, making it useful for domain availability checks and monitoring.
Users can customize their requests by specifying the domain name they wish to query in the API endpoint. The API does not require additional parameters for basic lookups.
Typical use cases include checking domain availability, monitoring domain status changes, and retrieving registrar information for domain management or transfer purposes.
Data accuracy is maintained through the RDAP protocol, which is designed to provide up-to-date and reliable domain registration information sourced directly from registrars.
If the API returns partial or empty results, it may indicate that the domain is unregistered or that the queried domain does not exist. Users should verify the domain name and try again.
