How this service works
Registration facts for a domain from RDAP: registrar, created, expires, status and nameservers, with age and expiry flags.
Output
A JSON object containing: domain name, registrar, created/updated/expires timestamps, array of domain status codes, list of nameservers, age in days, days until expiry, DNSSEC signed flag, a human-readable verdict and summary, the RDAP source URL, and flags for degraded data or unchecked items.
Example use cases
Fraud risk screening for new domains
“Check the registration details for quickloans-apply.com — I need to know how old it is, who the registrar is, and whether it's about to expire, so I can assess if it looks suspicious.”
Domain expiry monitoring for IT team
“Pull the RDAP registration info for acmecorp.io and tell me how many days until it expires and what its current domain status is.”
Due diligence on acquisition target
“I'm evaluating a company and want to understand their domain history — can you get me the registration facts for techventures.net, including when it was created, the registrar, and any status flags?”
Technical details
Endpoint
GEThttps://domain-dns.x402tookit.com/domain-registration?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative registration metadata for a domain (registrar, age, expiry, status, nameservers) sourced from RDAP — the modern, structured replacement for WHOIS. Prefer this over generic WHOIS scrapers when you need machine-readable, standardized output. Ideal for fraud detection workflows (detecting newly registered domains), domain portfolio management, and pre-purchase due diligence. Choose sibling endpoints for DNS record lookups, DNSSEC validation, or email authentication grading.
Side effects
- Domain not found in RDAP (unregistered or unsupported TLD) — returns null fields or empty response
- Invalid domain format — query fails or returns error
- RDAP registry unavailable for the TLD — degraded flag set, partial data returned
- Network timeout reaching upstream RDAP server — degraded or error response
- Punycode/IDN domains may need proper encoding before querying
