How this service works
Domain registration facts via RDAP - registrar, creation, expiry and last-change dates, domain age, status codes, nameservers and DNSSEC for any domain
Output
Returns structured RDAP data for the queried domain including: registrar name, registration creation date, expiry date, last-changed date, computed domain age, domain status codes (e.g. clientTransferProhibited), nameserver hostnames, and DNSSEC configuration status.
Example use cases
Pre-acquisition domain vetting
“Before we bid on example.io, look up its RDAP record and tell me how old the domain is, who currently holds the registration, when it expires, and what nameservers it's pointing at.”
Expiry monitoring alert setup
“Check the RDAP data for mybusiness.com and tell me the exact expiry date and current status codes so I can figure out if we're at risk of losing it soon.”
Security due-diligence check
“I'm investigating a suspicious link from competitor-site.net — can you fetch its RDAP registration facts, including registrar, creation date, domain age, status flags, and whether DNSSEC is configured?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/domain/rdap/:domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable registration metadata (registrar, dates, nameservers, DNSSEC, status codes) for any domain via the modern RDAP protocol. Prefer it over raw WHOIS scraping for consistent, parseable JSON output. Ideal for domain vetting, expiry monitoring, security research, and data enrichment pipelines that operate per-domain at low cost.
Side effects
- Domain not found in RDAP registry — returns error or empty result for unregistered or ccTLD domains with limited RDAP coverage
- Invalid domain format — malformed domain strings return a validation error
- Registry timeout — upstream RDAP registry may be slow or unreachable, causing latency or failure
- Rate limiting — excessive calls may be throttled
- Newly registered domains may have incomplete or delayed RDAP data
