Atom operates a public Registration Data Access Protocol (RDAP) service in accordance with the ICANN Registration Data Policy (RDP) and our accreditation obligations.
RDAP is the modern replacement for WHOIS. It provides domain registration data in a standardized, structured format and allows for privacy-aware display of information consistent with applicable data-protection laws.
1. What is RDAP?
The Registration Data Access Protocol (RDAP) delivers domain registration details in a structured format defined by ICANN and the Internet Engineering Task Force (IETF). It replaces the legacy WHOIS system and improves:
- data consistency across registrars and registries
- internationalization and technical reliability
- privacy controls by allowing granular redaction of personal data
2. Access to Atom’s RDAP Service
Our RDAP service is publicly accessible as required by ICANN and is discoverable through ICANN’s RDAP bootstrap directory, which lists all accredited registrars and their official endpoints.
- For technical users, RDAP queries can be made through Atom’s registered endpoint as published in the IANA registrar bootstrap file.
- To prevent automated scraping and data misuse, Atom does not publish the direct RDAP base URL on this page.
- Requests made through the IANA RDAP system will resolve automatically to our live service.
3. What Data RDAP Displays
RDAP provides limited domain registration data, including:
- Domain name, registration and expiration dates, and status
- Registrar name (Atom Domains LLC)
- Registry operator information
- Nameservers and DNSSEC status
Depending on the TLD and privacy laws, the following may be redacted or omitted:
- Registrant, admin, or tech contact details (e.g., email, phone, address)
- Any data protected under privacy regulations such as the GDPR or applicable national laws
4. Data Privacy and Disclosure
Atom balances transparency with privacy. We only display information that ICANN policy requires to be public and that is lawful under applicable data-protection regulations.
- Disclosure of additional registration data may occur:
- in response to valid legal orders, law-enforcement requests, or ICANN compliance inquiries, or
- with the registrant’s explicit consent.
For details, see our Privacy Policy and WHOIS & Registration Data Policy.
5. Acceptable Use and Rate Limits
Use of Atom’s RDAP service is subject to the following conditions:
- Queries must not be excessive, automated at scale, or used for spam, data mining, or marketing purposes.
- Atom may implement rate-limiting, CAPTCHA, or access restrictions to protect against abuse.
- The information provided is for informational purposes only and does not guarantee domain ownership or availability.
By using our RDAP service, you agree to these terms and our RDAP Terms of Service.
