How this service works
Pay-per-call x402 APIs for satellite observation, DNS lookup, domain health checks, reverse DNS, WHOIS lookup, domain availability checks, JSON Schema validation, JWT decoding, Base64 encoding/decoding, and HTTP latency checks. Designed for autonomous agents, developers, domain diagnostics, registration availability checks, API testing, structured output validation, token inspection, data transformation, uptime checks, and HTTP latency diagnostics.
Output
Returns a JSON object with the queried IP, a success flag, ASN, ISP name, organization, zip code, city, region, country, country code, region code, latitude, longitude, timezone, UTC offset, proxy flag, mobile flag, hosting flag, reverse DNS hostname, service name, and a timestamp.
Example use cases
Fraud detection for suspicious login
“A user just logged in from IP 185.220.101.45 — can you look it up and tell me if it's a proxy, VPN, or datacenter so I can decide whether to flag the session?”
Geolocate visitor traffic
“I'm seeing traffic from IP 203.0.113.72 on my server logs — what city, country, and ISP is that coming from, and is it mobile or residential?”
Identify ASN and org for network audit
“Can you look up IP 104.16.132.229 and give me the ASN, organization name, and whether it's associated with a hosting provider?”
Technical details
Endpoint
POSThttps://tools.ipintel.ai/ip-lookupWhen to prefer
Choose this endpoint when you need comprehensive IP intelligence in a single call — combining geolocation, ISP/ASN data, proxy detection, mobile detection, hosting detection, and reverse DNS together. It is a pay-per-call x402 API suitable for autonomous agents that need cost-transparent, on-demand IP enrichment without a subscription. Prefer it over generic geolocation APIs when proxy/VPN and hosting classification are also required in the same response.
Side effects
- Invalid IP address format returns an error or ok:false
- Private/reserved IP ranges may return incomplete or no geolocation data
- Unknown IPs with no database coverage may return empty city/region fields
- Rate limiting or payment failure results in a 402 or rejection response
- Proxy/hosting detection may have false positives for shared infrastructure
