SYS.01
Threat Vectors

Data that powers decisions.

From stopping payment fraud to enforcing digital rights, see how top engineering teams use our privacy detection API to protect their platforms.

FinTech & Payments

Block bad actors masking their IPs to execute chargebacks, account takeovers, or bypass KYC checks. Step-up authentication intelligently.

AI & Scraping Defense

Protect proprietary datasets. Identify and block headless browsers, residential proxies, and datacenters attempting to harvest your content.

Gaming & Anti-Cheat

Maintain competitive integrity. Block players using VPNs to evade hardware bans, manipulate ping, or bypass regional release locks.

Media & Streaming

Enforce geographical licensing rights flawlessly. Stop proxy-based region spoofing and ensure your CDNs serve localized assets to genuine viewers.

AdTech & Analytics

Eradicate click fraud and polluted bot traffic. Ensure your ad spend and geo-targeting algorithms hit real local users, not server farms.

Enterprise SOC & SIEM

Enrich your threat intelligence pipelines. Ingest proxy signals into your SIEM to drop malicious inbound connections before they probe you.

SYS.02
Engine Specs

Privacy first.
Uncompromising accuracy.

Engineered to give developers deterministic threat data without sacrificing user privacy or application performance.

The No Logs Guarantee

We process IPs entirely in-memory and drop them the millisecond the request finishes. No request logging, no shadow databases. Absolute privacy by design.

Deterministic Accuracy

Hard data over guesswork. We avoid probabilistic heuristics to ensure zero false positives for your real, paying users.

Universal Protocol & CIDR Support

Our engine natively processes both IPv4 and IPv6 addresses without requiring format conversions. Need to analyze entire subnets? Send CIDR notations directly to the API for sweeping threat coverage.

Datacenter Mapping

Instantly identify traffic from hosting providers and cloud networks to stop automated botnets at the network layer.

Sub-10ms Edge Engine

Built from the ground up in Rust. Secure your critical paths (like logins and checkouts) without the latency tax.

Developer-First Simplicity

Drop-in security in 5 minutes. No bloated SDKs or complex handshakes. Just a blazing-fast REST endpoint returning predictable JSON.

EU Data Sovereignty

Our entire infrastructure operates exclusively within the European Union. We guarantee bulletproof GDPR compliance without shady cross-border routing. Your users' data never leaves the EU.

SYS.03
Implementation

Zero dependencies.
Infinite scale.

Stop wrestling with bloated SDKs and outdated local databases. Our REST API is designed to be integrated at the edge, in your middleware, or directly within your application logic in under 5 minutes.

01

Pass the IP

Send the incoming request IP to our edge network.

02

Sub-10ms Analysis

We query our in-memory threat graph instantly.

03

Actionable JSON

Parse the boolean flags to block, challenge, or allow.

bash
$> curl -X GET https://api.proxytracer.com/v1/check/109.70.100.3
-H "Authorization: Bearer proxy_······"
# Response (8ms)
{
  "ip": "109.70.100.3",
  "proxy": true
}
