IP Geolocation API
Geolocate any IP address -- country, city, ISP, ASN, VPN/proxy/Tor detection. IPv4 and IPv6 support. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
{
"mcpServers": {
"ip-geolocation": {
"url": "https://ip-geolocation.api.klymax402.com/mcp"
}
}
}
Quickstart -- HTTP (x402)
curl "https://ip-geolocation.api.klymax402.com/api/lookup?ip=..."
# -> 402 Payment Required, with an x402 payment challenge in the response body
Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

{"ip":"8.8.8.8","country":"United States","countryCode":"US","region":"California","city":"Mountain View","latitude":37.386,"longitude":-122.084,"timezone":"America/Los_Angeles","isp":"Google LLC","asn":"AS15169","isVPN":false,"isProxy":false,"isTor":false}
When to use: fraud detection, content localization, access control by region, analytics enrichment, and bot detection.

ip_lookup_geolocation_batch
Use this when you need to geolocate multiple IP addresses at once (up to 20). Returns an array of geolocation results in JSON.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
ips | array | yes | Array of IP addresses to lookup (max 20) |
