Resolve a single IPv4/IPv6 address to its full network identity in one call: the Autonomous System number, the authoritative AS holder/operator (RIPEstat), the ISP + organization, whether the AS is currently announced, the RIR/IANA allocation block the AS sits in, and country/region/city + coordinates + timezone. One join that turns an IP into "who runs this network and where" -- the lookup network-forensics, abuse triage, and fraud agents otherwise stitch together from a geo API plus a separate BGP source. Composes geo IP data + RIPEstat (RIPE NCC, CC BY 4.0); the routing/holder block degrades independently, with per-source status returned. Distinct from net.asn (AS-number first) and geo.ip (geo only): this is IP-first and joins both.
/api/net/ip-resolvePAYMENT-SIGNATURE.The ip resolve API is a pay-per-call net endpoint built for AI agents and autonomous software. Resolve a single IPv4/IPv6 address to its full network identity in one call: the Autonomous System number, the authoritative AS holder/operator (RIPEstat), the ISP + organization, whether the AS is currently announced, the RIR/IANA allocation block the AS sits in, and country/region/city + coordinates + timezone.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in ip resolve data source for an agent tool-use loop, an MCP host, or a backend that needs net data on demand without onboarding to yet another vendor portal.
