## Tools (as reported by the server, not verified)

- `domain-lookup`: Look up normalized RDAP registration data \(registrar, status, dates, nameservers, contacts\) for a domain name.
- `bulk-domain-lookup`: 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`: Look up normalized RDAP allocation data \(network range, holder, country, status, geofeed URL\) for an IP address or CIDR block.
- `asn-lookup`: Look up normalized RDAP data \(holder, country, status, registration dates\) for an autonomous system number.
- `nameserver-lookup`: Look up normalized RDAP data \(IP addresses, status, sponsoring registrar\) for a nameserver hostname.
- `entity-lookup`: 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`: 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.
