Questions about the API

What TLDs are supported?
We support all major gTLDs (.com, .net, .org, .info, etc.) and most ccTLDs. Coverage includes over 1,500 TLD extensions.
Is registrant contact information available?
Due to GDPR and privacy regulations, most registrars now redact personal contact information. Our API returns whatever data is publicly available in WHOIS records.
How fresh is the WHOIS data?
We query WHOIS servers in real-time for each request. Data reflects the current state of the domain registration.
Can I check domain expiration dates?
Yes, the expiryDate field shows when the domain registration expires. Use this for monitoring domain portfolios or identifying expiring domains.
What are EPP status codes?
EPP (Extensible Provisioning Protocol) status codes indicate the domain state - whether it can be transferred, deleted, or updated. Codes like "clientTransferProhibited" mean the domain is locked.
Can I use this for bulk domain lookups?
Yes, our API supports high-volume queries. Contact us for enterprise rate limits if you need to check thousands of domains.
