Ip Geolocation X402 MCP Server

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

ip_lookup_geolocation

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

Parameters

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

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.

Not for: single IPs (use ip_lookup_geolocation), domain data (use domain_lookup_intelligence).

• "Geolocate an IP address"
• "Geolocate multiple IP addresses at once (up to 20)"
