SiteCheck Web Intel IP Geolocation & ASN Lookup is a paid API for AI agents from api.webintel-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).
Resolves an IPv4 or IPv6 address to its BGP prefix, origin AS number, AS holder name, announcement status, and coarse country/coordinates via RIPEstat

How this service works
IPv4 or IPv6 address → covering BGP prefix, origin AS number and holder name, whether the prefix is announced, and a coarse country and map point, all from RIPEstat. Location is an estimate (a block-level database), not a street address; the city is often empty.
Output
Returns the covering BGP prefix for the IP, the origin AS number and AS holder/organization name, whether that prefix is currently announced in BGP, and a coarse geolocation including country code and approximate lat/lng coordinates (block-level estimate from RIPEstat, city often absent).
Example use cases
Investigating suspicious login origin
“I have a suspicious login from IP 185.220.101.34 — can you tell me what autonomous system and country it belongs to, and whether that BGP prefix is actively announced?”
Enriching server inventory with network info
“What ASN, BGP prefix, and country is associated with the IP 104.21.0.1? I'm building a network map of our infrastructure.”
Threat intel triage for security team
“We're seeing traffic from 45.142.212.100 — look up its origin AS number, holder name, and covering BGP prefix so I can figure out if it's a known hosting provider or residential network.”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/security/ip-geolocation-asn?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need BGP-level network attribution (ASN, prefix, holder) combined with coarse geolocation in a single call, especially for security investigation, network enrichment, or routing analysis. It is better than pure geolocation APIs when AS/BGP data matters. For precise street-level location, use a dedicated commercial geolocation service. For blacklist/reputation checks, pair with complementary endpoints like CI Army or Talos on the same platform.
Side effects
- Invalid or malformed IP address returns an error response
- Private/reserved IP ranges (e.g. 192.168.x.x, 10.x.x.x) may return no BGP data
- IP not covered by any announced prefix returns no ASN data
- RIPEstat upstream unavailability causes timeout or 502-class errors
- IPv6 addresses may have less complete geolocation data than IPv4
