Look up registration data for many domains in one run using RDAP (Registration Data Access Protocol), the ICANN-standard successor to port-43 WHOIS. The Actor reads the official IANA RDAP bootstrap file (data.iana.org/rdap/dns.json) to find the right registry server for each TLD, then queries it directly.
What you get per domain
| Field | Description |
|---|---|
registrar / registrarIanaId | Sponsoring registrar name and IANA ID |
createdAt, updatedAt, expiresAt | Registration, last-changed and expiration dates (as published by the registry) |
domainStatus | EPP status codes (e.g. client transfer prohibited) |
nameservers | Delegated name servers |
dnssecSigned | Whether the delegation is DNSSEC-signed |
rdapServer | The registry RDAP server that answered |
No personal data is collected. Registrant, admin and tech contact entities are ignored; only registrar-level and domain-level fields are output.
How to use
- Click Start with the prefilled sample domains to see the output format.
- Replace the list with your own domains (URLs are accepted;
www.is stripped). - Export results as JSON, CSV or Excel, or call the Actor through the API.
Use cases
- Expiry monitoring for a domain portfolio
- Checking registrar and name-server setup across client domains
- Enriching lead or vendor lists with domain age
Pricing
Pay per event: a small start fee plus a fee per domain successfully returned. Domains that fail (invalid, not registered, TLD without RDAP, registry error) are not written to the dataset and are not charged; they are saved to the key-value store record FAILED_DOMAINS with the reason.
Limitations
- Some ccTLDs do not publish an RDAP server in the IANA bootstrap; these are reported as
no_rdap_server. - Field coverage depends on each registry. Thin registries (e.g. .com) return registrar-level data only.
- Lookups are rate-limited (low default concurrency, batch delay, retry with backoff on 429) to respect registry limits.
Data sources and terms
Data comes from public RDAP services operated by domain registries, located via the IANA bootstrap registry. Use the output in line with each registry's RDAP terms of use. This Actor is not affiliated with ICANN, IANA or any registry.
