Quick cURL

curl -s "https://closriq.com/api/ip-check.php?ip=8.8.8.8" \
  -H "X-API-Key: YOUR_API_KEY"

Returns JSON including fraud_score, flags, and api_usage.

1) Get an API key

Create an account and pick any plan to start your 10-day trial. Your API key appears in the dashboard.

2) Call the endpoint

Send the key as X-API-Key or ?api_key=. The API tracks usage automatically.

3) Enforce in your app

Block or step-up-verify when high-risk flags are present (VPN, proxy, TOR, hosting, abuse history).

JavaScript example

Browser-side usage (recommended: call from your backend to keep keys private).

const ip = "8.8.8.8";

const res = await fetch("https://closriq.com/api/ip-check.php?ip=" + encodeURIComponent(ip), {
  headers: {
    "X-API-Key": "YOUR_API_KEY",
  }
});

const data = await res.json();
console.log(data.fraud_score, data.flags, data.api_usage);

What gets tracked
