How this service works
A hosted MCP server exposing utility tools any AI agent can call over HTTP — page-to-markdown, SEO audits, robots/sitemap checks, and more.
Output
Returns a JSON object containing the resolved IP's geographic information (country, region, city) and ASN details (ASN number, organization/ISP name), given a hostname or raw IPv4 address as input.
Example use cases
Security audit of suspicious traffic source
“I'm seeing traffic from 198.51.100.42 hitting my API — can you look up where that IP is located and which autonomous system it belongs to?”
Verify CDN or hosting provider location
“Can you check what country and ASN the hostname cdn.shopify.com resolves to? I want to confirm it's served from a US-based network.”
Enrich server inventory with network metadata
“I have the hostname mail.protonmail.com — can you get me the geolocation and ASN details so I can tag it in my infrastructure inventory?”
Technical details
Endpoint
POSThttps://papacasper.com/mcp/pay/ip_geolocation_asn_lookupWhen to prefer
Use this endpoint when you need quick, pay-per-use IP geolocation and ASN resolution without managing API keys for MaxMind or ip-api.com. Ideal for agents that need on-demand network enrichment at very low cost ($0.0003/call) via x402 micropayment, with no subscription required.
Side effects
- Invalid or unresolvable hostname returns an error or empty result
- Private/reserved IP ranges (e.g. 192.168.x.x, 10.x.x.x) may return no geolocation data
- Hostnames that don't resolve in DNS will fail lookup
- Payment failure (HTTP 402) if USDC balance is insufficient
