How this service works
Lookup WHOIS records and domain availability in JSON format. Provide the domain name via ?domain=example.com to query registrar, status, and expiration dates.
Output
A JSON object containing WHOIS data for the queried domain, including the registrar name, domain registration status (e.g. active, expired, pending deletion), expiration date, and domain availability indicator.
Example use cases
Domain expiration monitoring for portfolio
“Check the WHOIS record for mybrand.com and tell me the expiration date and current registration status so I know when I need to renew it.”
Verifying domain availability before purchase
“Is thefutureof.ai available to register? Look up its WHOIS record and tell me if it's taken or free.”
Investigating suspicious website ownership
“I got a phishing email from a link on suspicioussite.net — can you pull the WHOIS data for that domain and tell me who the registrar is and how long it's been registered?”
Technical details
Endpoint
GEThttps://percallapi.com/whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured JSON WHOIS data including registrar, status, and expiration for a specific domain, especially in agentic workflows that need to parse domain registration details programmatically. Prefer this over manual WHOIS lookups or scraping when you need reliable, machine-readable output at low per-call cost.
Side effects
- Domain not found or unregistered — may return empty or null WHOIS fields
- Invalid domain format passed via ?domain= parameter
- TLD not supported by upstream WHOIS service
- Rate limiting or payment failure resulting in 402 response
- Timeout if upstream WHOIS registry is slow to respond
