Api Endpoint

IPv4/IPv6 address inspector (canonical, integer, reverse DNS, scope)

IPv4 and IPv6 address inspector: one GET takes one address and returns its canonical and fully expanded form, its decimal integer and hex value, its reverse-DNS name (in-addr.arpa or ip6.arpa), and the special-purpose ranges it belongs to — private, loopback, link-local, multicast, documentation, carrier-grade NAT, unique-local, NAT64, 6to4, Teredo — as scope, flags and special_ranges. An IPv4-mapped IPv6 address also returns the embedded IPv4 address and its classification. curl: GET /ip?addr=2001:db8::1 . Response: {"version":6,"canonical":"2001:db8::1","expanded":"2001:0db8:...","scope":"documentation","flags":{...}}. global means outside the special-purpose ranges checked here; it is not a claim about reachability, ownership or reputation, and no DNS query is made. A missing, malformed, over-long or zone-id address is 400 before payment and before any charge. No keys, no account, one GET, one delivery — 0.001 USDC. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
