How this service works

Output
Returns a structured summary including the registrar name, domain creation date, expiry date, domain age, days remaining until expiry, status lock flags, and nameservers. If the domain appears unregistered, indicates it may be available to register. Response time is approximately 120ms.
Example use cases
Competitor domain age research
“Look up the WHOIS details for shopify.com — I want to know when it was registered, who the registrar is, and how many days until it expires.”
Check if a domain is available
“Can you run a WHOIS lookup on morningbloomcoffee.io and tell me if it's available to register or already taken?”
Expiry monitoring for owned domain
“Check the WHOIS record for myadventureblog.net and tell me how many days until it expires and what status locks are on it.”

Endpoint
POSThttps://agent.maddegen.art/hub/api/v1/tools/domain_whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, structured WHOIS metadata about a specific domain — including registrar, creation/expiry dates, status locks, and nameservers — without building your own WHOIS parsing pipeline. Particularly useful for domain availability checks, due diligence on competitor or acquisition targets, or monitoring expiry dates on domains of interest. Priced per call at $0.002 USDC, making it cost-effective for individual or moderate-volume lookups.
Side effects
- Invalid or malformed domain string returns an error
- Domain with restricted WHOIS privacy may return redacted registrant info
- TLDs not supported by the underlying WHOIS registry may return no data
- Network timeout or WHOIS server unavailability may cause lookup failure
- Newly registered domains may not yet appear in WHOIS records
