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
Returns a JSON object with the domain name, source attribution (ICANN RDAP via rdap.org bootstrap), domain status flags (e.g. clientTransferProhibited), expiry date, registration date, last changed date, registrar name, nameservers, and domain age in days.
Example use cases
Vendor domain ownership verification
“Before we sign a contract with this supplier, can you pull their RDAP data for their domain? I need to confirm the registrar, check the expiry date, and see if there are any status flags that might indicate problems.”
Domain portfolio renewal tracking
“I manage a bunch of company domains and need to know which ones are expiring soon. Can you look up the registration details for all of them and flag any that are expiring within the next 60 days?”
Competitor domain monitoring
“Check the RDAP details for our main competitor's website — I want to know when their domain registration expires, who their registrar is, and if there are any unusual status flags on their domain.”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/domain/rdapWhen to prefer
Use this endpoint when you need authoritative, structured domain registration metadata (expiry, registrar, nameservers, status flags) sourced directly from ICANN RDAP registries rather than scraping or third-party WHOIS services. Prefer this over generic WHOIS lookup tools when you need machine-readable JSON output, domain age calculations, or need to verify domain status flags as part of a business or vendor due-diligence workflow. Best for European business verification pipelines where domain ownership confirmation complements company registry checks.
Side effects
- Domain not found in RDAP registry — returns empty or 404-style response
- Invalid or malformed domain name input — query parameter validation error
- RDAP bootstrap registry temporarily unavailable — upstream timeout or 5xx
- Domain TLD not supported by RDAP bootstrap — partial coverage for some ccTLDs
- HTTP 402 returned if payment not completed via x402 protocol before retry
