How this service works
Domain WHOIS via RDAP: registrar, creation and expiry dates, status and nameservers. Input: a domain.
Output
A JSON object containing the queried domain name, the data source (RDAP), an array of domain status codes (e.g. clientTransferProhibited), ISO 8601 creation/expiry/updated timestamps, the registrar name, and an array of nameserver hostnames.
Example use cases
Domain expiry monitoring for brand protection
“Check the WHOIS details for mybrand.com — I need to know the expiry date and current status so I can make sure it doesn't lapse.”
Vendor domain due diligence
“Before we start working with this vendor, can you pull the WHOIS registration info for their domain acmecorp.io? I want to see how old it is, who the registrar is, and what nameservers they're on.”
Investigating a suspicious domain
“I got a phishing email from support@secure-paypal-login.com — can you do a WHOIS lookup on that domain to see when it was registered, who registered it, and what its current status is?”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable WHOIS/RDAP data for a domain, especially registrar identity, lifecycle dates, and nameservers. Prefer it over raw DNS lookups when you need registration metadata rather than DNS records, and over scraping traditional WHOIS when you need clean JSON output. It complements the sibling DNS lookup endpoint for a full picture of a domain's configuration.
Side effects
- Domain not found in RDAP — returns empty or error response for unregistered or TLDs without RDAP support
- Invalid domain input — malformed strings may return a validation error
- RDAP registry timeout — upstream RDAP server may be slow or unresponsive for certain TLDs
- Rate limiting — repeated rapid calls may be throttled by upstream RDAP servers
- Payment failure — the $0.001 USDC x402 micropayment must succeed before the query is executed
