Pay-per-call IP geolocation API: given any IPv4 or IPv6 address, return the physical location (city, region, country, postal code, latitude/longitude, timezone) plus network intelligence (ISP, organization, ASN, connection type). Use it to localize content, enforce geo-restrictions, detect VPN/proxy/Tor exit nodes, stop fraud, and enrich user or event records. No API key required; pay in USDC per lookup.
