How this service works
Use to vet a domain or URL before trusting it, or to check if a name is available. Registry RDAP data (the WHOIS successor) for up to 20 domains per call: registrar, created/expiry dates, age in days, status and transfer lock, nameservers, DNSSEC. Subdomains resolve to their registered domain. One flat price per call.
Output
For each queried domain, the agent receives: registrar name, creation date, expiry date, domain age in days, registration status flags, transfer lock status, nameservers list, and DNSSEC enabled/disabled. Subdomains are automatically resolved to their registered parent domain before lookup.
Example use cases
Vet a phishing suspect domain
“I got an email with a link to paypa1-secure.com — can you pull the RDAP registration data for it and tell me when it was created, who registered it, and if it looks sketchy?”
Bulk due diligence on competitor domains
“I need to check the registration age, registrar, and status for these five domains before our acquisition call: acmecorp.io, acmecorp.co, acmecorp.net, acmecorp.app, acmecorp.xyz”
Check domain availability before buying
“Is the domain morningbloomcoffee.com available, or is it already registered? If it's taken, can you tell me when it expires?”
Technical details
Endpoint
GEThttps://x402-tools-production-2755.up.railway.app/tools/domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative registry-level data (RDAP) about domain ownership, age, status, and security configuration — especially for trust-vetting, phishing detection, or due diligence workflows. Prefer it over simple DNS lookups when you need registrar, creation/expiry dates, or transfer lock details. Supports bulk queries of up to 20 domains per call at a flat rate, making it efficient for batch checks.
Side effects
- Domain not found in RDAP (unregistered or unsupported TLD) — returns empty or null record
- More than 20 domains supplied in a single call — request rejected
- Invalid domain format passed — parsing error returned
- RDAP registry temporarily unavailable for a TLD — partial results or timeout
- Network error reaching the upstream RDAP registry — 5xx response
