Ip Geolocation X402

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.

Tools

Tool	Method	Path	Price	Description
ip_lookup_geolocation	GET	/api/lookup	$0.008	Geolocate a single IP address

ip_lookup_geolocation

Use this when you need to geolocate an IP address. Returns full location and network data in JSON.

Parameters

Name	Type	Required	Description
ip	string	yes	IP address to lookup (e.g. 8.8.8.8)

Example response:

{"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.

Not for: domain data (use domain_lookup_intelligence), DNS records (use network_lookup_dns).

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)

Example response:

{"results":[{"ip":"8.8.8.8","country":"United States","city":"Mountain View","isp":"Google LLC","isVPN":false},{"ip":"1.1.1.1","country":"Australia","city":"Sydney","isp":"Cloudflare","isVPN":false}],"total":2}

When to use: bulk log analysis, batch fraud screening, and enriching analytics data with location info. More cost-effective than single lookups.
