VPN Proxy Detector API

GET

Spot visitors connecting through VPNs or datacenter servers.

VPN Proxy Detector checks any IP address to detect active VPN connections and cloud datacenter hosting. Lookups return boolean flags for VPN and datacenter status plus the verification date, with paid tiers adding Tor detection and risk levels.

About the VPN Proxy Detector API

A VPN and proxy detection API. 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.

What people use it for

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.

Ways to call it

One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

Questions.

Common questions about the VPN Proxy Detector API.

Read the docs →

Does it distinguish between consumer VPNs and cloud datacenter IPs?

Yes. The response separates whether an IP belongs to a commercial VPN service from whether it originates from a cloud provider or datacenter. This lets you enforce different policies for standard VPN users compared to automated hosting traffic.

How far does the Starter plan go for IP lookups?

Starter provides 200,000 credits each month, covering 20,000 IP lookups at 10 credits per call. That works out to about $0.0015 per check or $1.50 per 1,000 lookups. The Free plan includes 20 checks every month for testing your integration.

Do I get risk and threat levels on the Free plan?

No. The Free plan includes whether an IP is a VPN or datacenter, but risk level and threat level ratings require a paid subscription. Any paid plan, starting with Starter, returns both assessments alongside the detection flags.

How often is the VPN detection data updated?

The database updates daily to catalog newly active VPN nodes and hosting ranges. Every response also includes a timestamp indicating the exact date the IP address was last checked for VPN activity.

Can I use this detection data in a commercial SaaS product?

Yes, provided you are on a paid plan. Commercial use is allowed across all paid tiers, including Starter. You can evaluate incoming traffic to protect signups or control access in your application, though redistributing or reselling the raw IP data is prohibited.

Request parameters — GET /v1/vpndetector

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`ip`Required	string	`103.62.49.210`	The IP address you want to check for VPN usage ip

Example request

1
2

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

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.

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.

Response — GET /v1/vpndetector

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

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.

Field	Type	Example	Description
`ip`	string	`"103.62.49.210"`	The IP address that was checked for VPN usage
`is_vpn`	boolean	`false`	Whether the IP address is using a VPN service
`is_datacenter`	boolean	`true`	Whether the IP belongs to a datacenter or cloud provider
`is_tor`Premium	boolean	`false`	Whether the IP is a known Tor exit node; null if the Tor list could not be checked
`asn`Premium	string	`"AS137409"`	Autonomous System Number announcing the IP (e.g., AS16509); null if unrouted
`asn_name`Premium	string	`"GSLNETWORKS-AS-AP GSL Networks Pty LTD"`	Registered name of that AS (e.g., AMAZON-02), not always the company name
`checked_on`	string	`"2026-09-14"`	The date when the IP was last checked for VPN status
`risk_level`Premium	string	`"Moderate"`	Overall risk of the IP address: High for Tor exits and VPNs, Moderate for datacenter-only addresses, Low otherwise
`threat_level`Premium	string	`"Low"`	How strongly the IP anonymises its user: High for Tor exits, Moderate for VPNs, Low otherwise

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 10 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	VPN Proxy Detector calls	Per 1,000 calls
Free	Free	200	20	Free
Starter	$29.99	200,000	20,000	$1.50
Pro	$99.99	1,000,000	100,000	$1.00
Mega	$299.99	4,000,000	400,000	$0.75

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
