How this service works
Authoritative domain registration facts from the ICANN-mandated RDAP protocol (rdap.org bootstrap -> registry of record), normalized across all TLDs: registration/expiration/last-changed dates, computed age_days, registrar name, EPP status locks and nameservers. Query: ?domain=google.com (required). No personal data served. 24h cache.
Output
A normalized JSON object containing: registration/expiration/last-changed timestamps, computed age_days, registrar name, EPP status lock codes (e.g. clientTransferProhibited), and nameserver hostnames — all sourced from the authoritative ICANN RDAP registry of record for the queried TLD. Results are cached for 24 hours.
Example use cases
Example prompt
“Can you pull up the RDAP registration details for openai.com — I want to know when it was registered, when it expires, who the registrar is, its EPP status locks, and its nameservers?”

Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/domain/rdapWhen to prefer
Choose this endpoint when you need authoritative, normalized domain registration metadata (dates, registrar, EPP locks, nameservers) pulled directly from the ICANN-mandated RDAP registry of record for any TLD. Prefer it over WHOIS-based tools for standardized, machine-readable output without personal data concerns, and when you need reliable cross-TLD normalization with a computed domain age.
Side effects
- Missing domain parameter returns 400 or validation error
- Invalid or non-existent domain returns 404 or empty result
- Unsupported or new TLD with no RDAP bootstrap entry may return an error
- Registry RDAP endpoint temporarily unavailable causes upstream timeout or 502
- Payment not processed (x402 protocol) results in 402 Payment Required
