Free Website Safety Checker API for Developers — Integrate Scam Detection in Minutes

Why You Need a Website Safety API

If you're building an app where users submit URLs — a browser extension, a link shortener, a marketplace, a chat platform — you need a way to flag dangerous links before your users click them.

The problem? Threat intelligence is fragmented across dozens of sources. Google Safe Browsing covers phishing. VirusTotal covers malware. PhishTank covers community-reported phishing. Spamhaus covers spam domains. No single source gives you the full picture.

RiskScope's API solves this by aggregating 14+ threat intelligence sources into a single request that returns a 0-100 risk score.

How the RiskScope API Works

One request. One response. All the data you need.

curl -H "x-api-key: YOUR_API_KEY" \
  "https://riskscope.actvli.com/api/v1/lookup?domain=example.com"

The response includes:

• Risk score (0-100) — higher means more dangerous
• Risk level — low, medium, high, or critical
• Individual signals — each threat source's findings, with severity and description
• Signal dimensions — categorized as identity, technical, reputation, offer, or quality

Quick Start: JavaScript/Node.js

async function checkWebsite(domain) {
  const response = await fetch(
    `https://riskscope.actvli.com/api/v1/lookup?domain=${domain}`,
    { headers: { 'x-api-key': process.env.RISKSCOPE_API_KEY } }
  );
  const data = await response.json();

  if (data.risk_score > 50) {
    console.warn(`Warning: ${domain} has a risk score of ${data.risk_score}`);
  }

  return data;
}

---

Quick Start: Python

import requests
import os

def check_website(domain):
    response = requests.get(
        f"https://riskscope.actvli.com/api/v1/lookup?domain={domain}",
        headers={"x-api-key": os.environ["RISKSCOPE_API_KEY"]}
    )
    data = response.json()

    if data["risk_score"] > 50:
        print(f"Warning: {domain} scored {data['risk_score']}/100")

    return data

What Threat Sources Are Checked?

Every API call runs the domain against:

Source	What It Detects
Google Safe Browsing	Phishing, malware, social engineering
VirusTotal	Malware from 70+ scanning engines
PhishTank	Community-verified phishing URLs
OpenPhish	ML-based phishing detection
URLhaus	Active malware distribution
ThreatFox	Indicators of compromise
Feodo Tracker	Botnet C&C servers
Spamhaus DBL	Spam and abuse domains
AbuseIPDB	IP reputation and abuse history
StopForumSpam	Known fraud sources

Plus RiskScope's own analysis: WHOIS/DNS age, SSL certificate validation, content analysis, and more.
