Domain Lookup Tool
Look up normalized RDAP registration data (registrar, status, dates, nameservers, contacts) for a domain name.
Bulk Domain Lookup Tool
Look up normalized RDAP registration data for several domain names in one pooled call. Requires a Pro or Business plan; every domain in the batch counts against the quota.
Ip Lookup Tool
Look up normalized RDAP allocation data (network range, holder, country, status) for an IP address or CIDR block.
Asn Lookup Tool
Look up normalized RDAP data (holder, country, status, registration dates) for an autonomous system number.
Nameserver Lookup Tool
Look up normalized RDAP data (IP addresses, status, sponsoring registrar) for a nameserver hostname.
Entity Lookup Tool
Look up normalized RDAP data for an RIR entity handle — an organization or contact identifier such as "GOGL" or "ORG-RIEN1-RIPE". Only ARIN, RIPE, APNIC, LACNIC and AFRINIC handles resolve; a domain's registrar or registrant comes from domain-lookup instead.
Tlds Tool
List the TLDs this API can query, or describe one: which RDAP server answers for it, since when it has been supported, and how often that server fills each field. Metadata, so it never counts against the monthly quota.
