What is the ipquery.io API?

ipquery.io is a free, key-free IP intelligence API returning geolocation, ISP and ASN data alongside risk signals — whether the address is a VPN, proxy, Tor exit node, datacentre IP or known abuser.

Most free IP APIs stop at geolocation. ipquery adds a risk object flagging VPNs, proxies, Tor exit nodes, datacentre ranges and known abusive addresses, which is the part fraud and abuse prevention actually needs.

Getting those signals without an API key is genuinely unusual — comparable commercial services charge for exactly this data. It is worth treating the flags as strong hints rather than certainties, since VPN detection is inherently imperfect.

How to use the ipquery.io API

Every request below was executed against the live API on 19 Aug 2026, and the response shown is the real body it returned — not an illustration.

1. Look up IP intelligence data

GET https://api.ipquery.io/8.8.8.8

curl

curl 'https://api.ipquery.io/8.8.8.8'

JavaScript (fetch)

const res = await fetch("https://api.ipquery.io/8.8.8.8");
if (!res.ok) throw new Error(`Request failed: ${res.status}`);
const data = await res.json();
console.log(data);

Python (requests)

import requests

res = requests.get("https://api.ipquery.io/8.8.8.8", timeout=20)
res.raise_for_status()
print(res.json())

Response — HTTP 200

Common errors and how to fix them

Risk flags on legitimate users

Many people use VPNs for privacy.

Fix: Treat the flags as signals for additional verification, not as grounds for an automatic block.

Private IP returns an error

RFC1918 addresses cannot be geolocated.

Fix: Filter private ranges before querying.

Inconsistent city data

IP geolocation is approximate everywhere.

Fix: Do not present the city as authoritative.

ipquery.io API — frequently asked questions

Is ipquery.io free?

Yes, free with no API key, which is unusual for an API that includes VPN and proxy detection — comparable commercial services charge for those signals.

Can it detect VPNs reliably?

It provides strong signals, but VPN detection is never perfect. New endpoints appear constantly and residential proxies are hard to spot. Use it to trigger extra verification, not to block outright.

What does is_datacenter mean?

The IP belongs to a hosting provider rather than a consumer ISP. That often indicates a bot, scraper or VPN rather than a person browsing from home.

Does it work over HTTPS?

Yes, HTTPS with no key, which makes it usable where ip-api's HTTP-only free tier is blocked as mixed content.
