How this service works
IP to ASN and carrier inference: resolve any IP to its Autonomous System (ASN), ISP/org, mobile flag, proxy/hosting signals, and an inferred carrier and connection type. A lightweight, agent-callable counterpart to telco Network-as-Code device-location APIs — no carrier contract, no onboarding, pay per call in USDC on Base. Built for fraud screening, geo-routing, and SIM-swap-style risk signals in agentic payment pipelines.
Output
Returns the ASN number and name, ISP/organization name, a mobile device flag, proxy/VPN/hosting detection signals, an inferred mobile carrier name, and a connection type classification (e.g. mobile, broadband, hosting) for the queried IP address.
Example use cases
Payment fraud IP screening
“Before processing this payment, check whether IP 198.51.100.22 is coming from a real mobile network or a proxy/hosting provider — I need ASN and carrier details to assess SIM-swap risk.”
Geo-routing by connection type
“I need to route this user's request differently depending on whether their IP 104.28.15.3 is on a mobile carrier vs a fixed broadband ISP — can you resolve the carrier and connection type?”
Ad-traffic quality check
“Can you tell me if the IP 185.220.101.5 is from a legitimate ISP or looks like a data center or proxy? I want the ASN, org, and mobile flag to filter bot traffic.”
Technical details
Endpoint
GEThttps://apiwitchcraft.duckdns.org/ip/carrierWhen to prefer
Use this endpoint when you need lightweight, pay-per-call IP-to-carrier and ASN enrichment without a carrier contract or enterprise onboarding — ideal for agentic payment pipelines needing SIM-swap risk signals, fraud screening by connection type, or geo-routing decisions based on network metadata. Prefer this over full telco Network-as-Code APIs when you lack carrier relationships or need a simple per-IP lookup paid in USDC on Base.
Side effects
- Invalid or malformed IP address returns an error response
- Private/reserved IP ranges (RFC1918, loopback) may return empty or error results
- Very new IP allocations may not yet appear in ASN data
- Carrier inference may be unavailable for some regional or tier-3 ISPs
- Service unavailability if the underlying GeoIP/ASN database is stale or unreachable
