ツール（7）
⚪domain-lookup(domain, follow, whois)
Look up normalized RDAP registration data (registrar, status, dates, nameservers, contacts) for a domain name.
入力スキーマ
{
"type": "object",
"properties": {
"domain": {
"description": "The domain name to look up, e.g. \"example.com\". Unicode (IDN) names are accepted.",
"type": "string"
},
"follow": {
"description": "Follow the registrar RDAP link for richer data on thin registries such as .com and .net. Slower; defaults to false.",
"default": false,
"type": "boolean"
},
"whois": {
"description": "Set false to refuse the WHOIS fallback, so a TLD with no RDAP server errors instead of answering over port 43. Defaults to true.",
"default": true,
"type": "boolean"
}
},
"required": [
"domain"
]
}⚪bulk-domain-lookup(domains, follow, whois)
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.
入力スキーマ
{
"type": "object",
"properties": {
"domains": {
"description": "The domain names to look up, e.g. [\"example.com\", \"example.net\"]. Between 1 and 10 per call. Unicode (IDN) names are accepted.",
"minItems": 1,
"maxItems": 10,
"items": {
"type": "string"
},
"type": "array"
},
"follow": {
"description": "Follow the registrar RDAP link for richer data on thin registries such as .com and .net. Slower; defaults to false.",
"default": false,
"type": "boolean"
},
"whois": {
"description": "Set false to refuse the WHOIS fallback for every domain in the batch, so a TLD with no RDAP server returns not_supported. Defaults to true.",
"default": true,
"type": "boolean"
}
},
"required": [
"domains"
]
}⚪ip-lookup(ip, prefix)
Look up normalized RDAP allocation data (network range, holder, country, status, geofeed URL) for an IP address or CIDR block.
入力スキーマ
{
"type": "object",
"properties": {
"ip": {
"description": "IPv4 or IPv6 address, e.g. \"8.8.8.8\" or \"2001:4860:4860::8888\".",
"type": "string"
},
"prefix": {
"description": "Optional CIDR prefix length, e.g. 24. Must be 0-32 for IPv4 or 0-128 for IPv6.",
"type": "integer"
}
},
"required": [
"ip"
]
}⚪asn-lookup(asn)
Look up normalized RDAP data (holder, country, status, registration dates) for an autonomous system number.
入力スキーマ
{
"type": "object",
"properties": {
"asn": {
"description": "Autonomous system number, e.g. \"15169\" or \"AS15169\".",
"type": "string"
}
},
"required": [
"asn"
]
}⚪nameserver-lookup(host)
Look up normalized RDAP data (IP addresses, status, sponsoring registrar) for a nameserver hostname.
入力スキーマ
{
"type": "object",
"properties": {
"host": {
"description": "Nameserver hostname, e.g. \"ns1.example.com\".",
"type": "string"
}
},
"required": [
"host"
]
}⚪entity-lookup(handle)
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.
入力スキーマ
{
"type": "object",
"properties": {
"handle": {
"description": "RIR entity handle, e.g. \"GOGL\" (ARIN) or \"ORG-RIEN1-RIPE\" (RIPE).",
"type": "string"
}
},
"required": [
"handle"
]
}🟢tlds(tld, server, since)
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.
入力スキーマ
{
"type": "object",
"properties": {
"tld": {
"description": "A single TLD to describe, e.g. \"com\" or \".io\". Omit to list every supported TLD by name.",
"type": "string"
},
"server": {
"description": "List only the TLDs served by this host, RDAP or WHOIS, e.g. \"rdap.verisign.com\". Ignored when \"tld\" is given.",
"type": "string"
},
"since": {
"description": "List only the TLDs added after this ISO 8601 date, e.g. \"2026-01-01\". Ignored when \"tld\" is given.",
"type": "string"
}
}
