# ip402.xyz > Paid IP geolocation + ASN lookup for agents. Send an IPv4/IPv6 address, get normalized geolocation and network data back. Payment is the access control — no accounts, no API keys. ## Endpoint - GET https://ip402.xyz/v1/geo?ip=&lang= - Price: $0.01 USDC per lookup (fixed). - Payment rails: x402 (USDC on Base & Solana mainnet) and Tempo MPP (charge, Tempo mainnet). The first request returns HTTP 402 advertising every rail on its own header; pay with any client and retry. ## Parameters - ip (required): IPv4 or IPv6 literal, e.g. 8.8.8.8 or 2001:4860:4860::8888 - lang (optional): localized GeoIP name preference, e.g. en, zh-CN. Defaults to en. ## Output JSON: normalized geolocation (country, city, location, time zone) and network (asn, organization) for the IP. ## Discovery - OpenAPI 3.1 + payment terms: https://ip402.xyz/openapi.json - Indexed on Coinbase CDP Bazaar (x402) and the MPP registries (Tempo).
