One Endpoint. Drop-In Fast.

Authenticate with a Bearer token. Every plan returns the same shape — your code never changes when you upgrade or scale.

  • Bearer auth or ?token= query
  • GET /v1/lookup/{ip}
  • POST /v1/lookup with rich context
  • POST /v1/batch up to 100 IPs

Frequently Asked Questions

What is an IP lookup, and what data does Lookip return?+

An IP lookup resolves an IPv4 or IPv6 address to facts about the network and location behind it. Lookip returns city, region, country, coordinates, accuracy radius, timezone, ASN and organization, mobile carrier signals, plus VPN, proxy, Tor, relay and residential-proxy detection.

Is there a free tier?+

Every new account gets $5 of credit on signup — enough for roughly 33,000 LITE lookups or 3,800 MAX lookups. No credit card required to start.

Do you support IPv6?+

IPv6 is a first-class citizen. The same endpoint, same shape, same plan limits — no upcharge. Hand the API any address that conforms to RFC 4291 and you get the same response back.

How accurate is the geolocation?+

For consumer IPs, expect city-level accuracy in most populated regions, with an explicit accuracyRadiusKm field so you can decide how much to trust each result. Mobile and CGNAT ranges are inherently noisier, and we flag them so your code can route differently.

Can I detect VPNs, proxies, and Tor exit nodes?+

Yes. Every response includes a threats object with isVpn, isProxy, isTor, isRelay and isResidentialProxy booleans, plus the named service when we can identify it. We also expose the percentage of recent days the IP has behaved like an anonymizer.

How fast is the API?+

LITE lookups stay under 5ms p95. MAX lookups stay under 200ms p95. The API ships with Bearer auth, a 100-IP batch endpoint, and request/quota headers so retries are easy.
