Reverse-resolve an IPv4 or IPv6 address to its PTR hostname(s). No PTR record returns an empty list. This is reverse DNS (PTR) — not ENS or onchain name resolution.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X GET 'https://dns.openverbs.com/v1/reverse' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch 'https://dns.openverbs.com/v1/reverse'
Endpoint: https://dns.openverbs.com/v1/reverse. Operated by dns.openverbs.com, not by Animica. Price and availability were correct at the last probe on 2026-10-01 and are set by the operator, who may change them.
Resolve DNS records for a hostname — A, AAAA, CNAME, MX, TXT, NS, SOA, CAA or SRV. NXDOMAIN or an absent record type returns an empty record set.
