How this service works
Look up a domain's registration facts in its registry's own RDAP service: registrar, creation/expiry/update dates, EPP status codes, nameservers and the DNSSEC delegation flag, with retry, cache and a durable audit receipt.
Output
Returns a structured record sourced from the domain's authoritative registry RDAP service, including: registrar name, domain creation/expiry/last-updated timestamps, EPP status codes (e.g. clientTransferProhibited), list of nameservers, and a boolean DNSSEC delegation flag. Also includes a durable audit receipt for compliance or logging purposes. Results may be cached for performance; retries are handled automatically on transient failures.
Example use cases
Domain expiry monitoring for portfolio
“Check the RDAP registration details for mybrand.com — specifically when it expires and its current EPP status, so I know if it's at risk of lapsing.”
Due diligence on acquired domain
“I'm buying the domain techstartup.io — can you pull its full registration record from RDAP including registrar, creation date, update date, nameservers, and DNSSEC flag so I can verify it's clean?”
Security audit for suspicious domain
“Look up the domain registration facts for suspicious-site.net — I want to see its registrar, EPP status codes, nameservers, and DNSSEC delegation status to assess if it looks legitimate.”

Endpoint
GEThttps://lookups.nl/domain/:nameWhen to prefer
Prefer this endpoint when you need authoritative, registry-sourced domain registration metadata (registrar, dates, EPP status, nameservers, DNSSEC) with built-in retry logic, caching, and an audit receipt — particularly for compliance workflows, domain portfolio monitoring, or security due diligence. It is more reliable than raw RDAP or WHOIS queries because it handles retries and caching transparently, and the audit receipt makes it suitable for regulated or auditable processes.
Side effects
- Domain not found in any RDAP registry — returns not found or 404-equivalent
- TLD not supported by RDAP protocol — registry may not expose an RDAP endpoint
- Registry RDAP service temporarily unavailable despite retries — returns timeout or service error
- Malformed domain name input — returns validation error
- Rate limiting from upstream registry — may result in delayed or failed response
