How this service works
Registrar, creation and expiry dates, status codes, nameservers and DNSSEC state for a domain, from the authoritative registry over RDAP.
Output
Returns structured RDAP data for the queried domain including: registrar name and IANA ID, registration creation date, last updated date, expiration date, domain status codes (e.g. clientTransferProhibited), delegated nameservers, and DNSSEC signed/unsigned state — sourced directly from the authoritative registry.
Example use cases
Domain expiry monitoring for portfolio
“Check the registration details for mybrand.com — specifically when it expires and what the current status codes are, so I can make sure we don't accidentally let it lapse.”
Security audit of third-party domain
“I need to verify whether acmecorp.io has DNSSEC enabled and who their registrar is — can you pull the RDAP record for that domain?”
Vendor due diligence check
“Before we sign this contract, can you look up the domain registration info for vendorxyz.com? I want to know when it was created, when it expires, and what nameservers it's using.”
Technical details
Endpoint
GEThttps://fittings.sh/v1/rdap/domainWhen to prefer
Use this endpoint when you need authoritative, registry-sourced domain registration metadata (registrar, dates, nameservers, DNSSEC) rather than cached or third-party WHOIS data. It is ideal for security audits, domain portfolio management, expiry monitoring, and vendor due diligence where accuracy and freshness matter. Prefer it over standard WHOIS lookups when DNSSEC state or structured machine-readable output is required.
Side effects
- Domain not found — returns an error if the domain is unregistered or the TLD's registry does not support RDAP
- Invalid domain format — malformed domain strings may return a validation error
- Unsupported TLD — some ccTLDs or new TLDs may not have RDAP-compliant registries
- Registry timeout — upstream RDAP registry may be slow or temporarily unavailable
- Rate limiting — excessive requests may be throttled
