How this service works
Use when an agent needs the age and WHOIS (RDAP) record of a domain, e.g. to spot freshly registered domains, qualify leads or vet links: registered or not, creation and expiry dates, age in days, registrar, EPP status codes, nameservers and DNSSEC. Accepts hosts like www.example.co.uk. $0.01 USDC on Base; charged only on 2xx, never for invalid input.
Output
Returns a structured object with: whether the domain is registered, creation date, expiry date, domain age in days, registrar name, EPP status codes array, nameservers list, and DNSSEC status — all sourced from the official RDAP protocol (WHOIS successor).
Example use cases
Fraud screening for new signups
“A new user just signed up with the domain quickpay-transfers.net — can you check how old that domain is, who registered it, and whether it looks newly created? I need to decide if it's risky.”
KYB due diligence on a vendor
“We're onboarding a new supplier who says they've been in business for 10 years. Their domain is acme-supplies.co.uk — can you pull the RDAP registration facts and tell me when it was first created and what registrar it's under?”
Link safety check before sharing
“Before I share this link with my team, can you check the domain safety-update-portal.com — specifically how long ago it was registered, its EPP status codes, and nameservers? I want to make sure it's not a recently spun-up phishing site.”
Technical details
Endpoint
POSThttps://api.facts402.com/domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, structured domain registration data from the RDAP protocol (the official WHOIS successor) rather than scraped WHOIS text. It is the right choice for fraud detection (newly registered domains are high risk), KYB/KYC pipelines, lead qualification (does this company's domain have real history?), and link safety checks. It handles international domains including multi-part TLDs like .co.uk. Prefer it over plain WHOIS parsers when you need machine-readable EPP status codes, DNSSEC status, and age-in-days without parsing freeform text.
Side effects
- Domain not found or unregistered — returns registered: false with no registration details
- Invalid or malformed domain input — returns validation error
- RDAP server for the TLD is unavailable or times out — returns upstream error
- TLD not supported by any RDAP server — partial or no data returned
- Rate limit or payment failure — returns 402 or 429 error
