Content-Type: application/json
{"jsonrpc":"2.0","id":1,"method":"tools/list"}dns_lookup — "Resolve [domain]" / "what IP does [site] point at" / "A records for [X]" — forward DNS lookup via HackerTarget, returning the A/AAAA/MX/NS/SOA records the resolver holds for a hostname. Use to check where a domain currently points, or to confirm a DNS change has propagated.reverse_dns — "What hostname is [IP]" / "reverse DNS for [address]" / "PTR record lookup" — reverse DNS (PTR) lookup via HackerTarget, mapping an IP address back to the hostname its owner published. Use to identify the operator behind an address in a log line. Returns nothing when no PTR record is set, which is common for cloud IPs.mtr — "Network path to [host]" / "where does traffic to [X] slow down" / "per-hop latency" — mtr report via HackerTarget, combining traceroute and ping into a per-hop table of loss and latency measured FROM HackerTarget's probe host, not from you. Use to see which network hop is losing packets. REQUIRES AN API KEY: HackerTarget gates this endpoint, and the keyless tier answers "error valid key required" (verified 2026-09-16).nping — "Is [host] up" / "ping [X]" / "round-trip time to [address]" — ICMP ping via HackerTarget, reporting reachability and round-trip time from HackerTarget's probe host. Use for a liveness check when you cannot ping from where you are. A host that blocks ICMP reads as down even when it serves traffic.dns_host_search — "Subdomains of [domain]" / "what hosts exist under [X]" / "find an admin or staging subdomain" — passive DNS host search via HackerTarget, listing known subdomains of a domain with their IPs, drawn from previously observed DNS data rather than by guessing names. Use for attack-surface inventory or to find a forgotten staging host.find_shared_dns — "What else uses this nameserver" / "domains sharing DNS with [X]" — shared-nameserver search via HackerTarget, listing other domains served by the same DNS server. Use to map the infrastructure footprint of an operator, or to see who else would be affected if a nameserver went down.geoip — "Where is [IP] located" / "what country is this address in" / "geolocate an IP" — IP geolocation via HackerTarget, returning country, state/region, city and coordinates for an address. City-level accuracy is approximate and a VPN or CDN address reports its datacenter, not its user. Use for coarse traffic attribution, never to locate a person.reverse_ip — "What else is hosted on [IP]" / "other sites on the same server" / "reverse IP lookup" — reverse IP lookup via HackerTarget, listing hostnames known to resolve to one address. Use to spot shared hosting or to find sibling properties of an operator. A CDN address returns many unrelated sites, so co-location is not evidence of common ownership.as_lookup — "Which ASN owns [IP]" / "what network is this address on" / "who is the upstream provider" — autonomous system lookup via HackerTarget, returning the ASN, the announced prefix and the network's name for an address. Use to attribute an address to a hosting provider, ISP or cloud region.whois — "Who owns [domain]" / "when does [X] expire" / "whois lookup" / "registrar for [site]" — WHOIS record via HackerTarget for a domain or IP: registrar, creation and expiry dates, nameservers, and whatever contact fields the registry still publishes. REQUIRES AN API KEY: HackerTarget gates this endpoint, and the keyless tier answers "error valid key required" (verified 2026-09-16). For keyless WHOIS use ripe_stat_whois.http_headers — "What headers does [site] return" / "what server runs [X]" / "check the security headers" / "does [site] redirect" — HTTP response headers fetched by HackerTarget, including status line, Server, redirect Location, and security headers such as HSTS and CSP. Use to fingerprint a stack or audit header hygiene without loading the page yourself.traceroute — "Traceroute to [host]" / "what route does traffic take to [X]" / "how many hops to [address]" — traceroute via HackerTarget, listing the routers between HackerTarget's probe host and the target. The path is measured from their network, not yours. REQUIRES AN API KEY: HackerTarget gates this endpoint, and the keyless tier answers "error valid key required" (verified 2026-09-16).subnet_lookup — "What is the range of [CIDR]" / "how many hosts in a /24" / "network and broadcast address for [X]" / "subnet calculator" — subnet arithmetic via HackerTarget, returning network address, broadcast address, usable host range, netmask and host count for a CIDR block. A pure calculation over the input; it does not probe the network.page_links — "What does [page] link to" / "extract every link from [URL]" / "outbound links on a page" — link extraction via HackerTarget, fetching one web page and returning the URLs it links to. Use to map a site section or find outbound references. One page only — it does not crawl, and it returns the links as published, not their fetched status.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
