VPN Proxy Detector

Detect VPN usage

OperationalCredits 10 per callp50 324msNetworkingStar

Overview

Send an IPv4 or IPv6 address to inspect its routing and hosting profile against daily updated network lists. The API flags whether the address routes through a commercial VPN or a cloud datacenter. Paid plans also return Tor exit node status, Autonomous System Numbers (ASN), and assigned risk and threat levels.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/vpndetector
curl "https://api.apiverve.com/v1/vpndetector?ip=103.62.49.210" \
  -H "x-api-key: your_api_key_here"

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

ParameterTypeDescription
ipRequiredstringThe IP address you want to check for VPN usage
ip

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Sample response
{
  "status": "ok",
  "error": null,
  "data": {
    "ip": "103.62.49.210",
    "is_vpn": false,
    "is_datacenter": true,
    "is_tor": false,
    "asn": "AS137409",
    "asn_name": "GSLNETWORKS-AS-AP GSL Networks Pty LTD",
    "checked_on": "2026-09-14",
    "risk_level": "Moderate",
    "threat_level": "Low"
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

FieldTypeExampleDescription
ipstring"103.62.49.210"The IP address that was checked for VPN usage
is_vpnbooleanfalseWhether the IP address is using a VPN service
is_datacenterbooleantrueWhether the IP belongs to a datacenter or cloud provider
is_torPremiumbooleanfalseWhether the IP is a known Tor exit node; null if the Tor list could not be checked
asnPremiumstring"AS137409"Autonomous System Number announcing the IP (e.g., AS16509); null if unrouted
asn_namePremiumstring"GSLNETWORKS-AS-AP GSL Networks Pty LTD"Registered name of that AS (e.g., AMAZON-02), not always the company name
checked_onstring"2026-09-14"The date when the IP was last checked for VPN status
risk_levelPremiumstring"Moderate"Overall risk of the IP address: High for Tor exits and VPNs, Moderate for datacenter-only addresses, Low otherwise
threat_levelPremiumstring"Low"How strongly the IP anonymises its user: High for Tor exits, Moderate for VPNs, Low otherwise

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

StatusMeaningWhat to do
400Input was rejectedRead error; it names the parameter.
401Key missing or invalidCheck the header name and the key value.
403Key valid, but not permittedA key restriction or IP allow-list; see key scoping.
429Rate limited, or out of creditsRead error to tell them apart; see rate limits.

Use cases

Fraudulent Signup Prevention
To stop fake account spam, security platforms verify visitor IPs at registration to block traffic originating from known commercial VPNs and cloud servers.
Streaming Rights Compliance
Media providers check playback requests against datacenter and VPN flags to enforce territorial broadcasting rights on copyrighted video catalogs.
Payment Gateway Screening
When an online order is submitted, checkout systems check the buyer IP to trigger extra authentication steps if it belongs to a datacenter network.
Ad Click Validation
Advertising networks filter invalid traffic by screening incoming ad impressions for datacenter hosting IPs before recording billable user interactions.
