Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

const url = "https://haveibeenpwned.com/api/v3/breachedaccount/[email protected]";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

import requests

url = "https://haveibeenpwned.com/api/v3/breachedaccount/[email protected]"
headers = {"X-API-Key": "YOUR_API_KEY"}

response = requests.get(url, headers=headers, timeout=30)
response.raise_for_status()
data = response.json()
print(data)

curl -X GET "https://haveibeenpwned.com/api/v3/breachedaccount/[email protected]" -H "hibp-api-key: YOUR_API_KEY" -H "User-Agent: MyApp"

What Can You Build?

// Scan for security threats
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const target = 'example.com';
const response = await fetch(`https://haveibeenpwned.com/API/v3`, { headers });
const data = await response.json();
console.log('Security scan result:', data);
const threats = data.threats || data.results || data;
console.log('Threat level:', threats.level || threats.risk || 'Check manually');

// Fetch vulnerability reports
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const response = await fetch(`https://haveibeenpwned.com/API/v3`, { headers });
const data = await response.json();
const vulns = data.vulnerabilities || data.results || data.data || [];
const items = Array.isArray(vulns) ? vulns : [vulns];
items.slice(0, 5).forEach(v => {
  console.log(`⚠️ ${v.name || v.cve || v.id}: ${v.severity || v.risk || 'Unknown'}`);
});

// Perform a security check
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const response = await fetch(`https://haveibeenpwned.com/API/v3`, { headers });
const report = await response.json();
console.log('Security report from HaveIBeenPwned:', report);
const score = report.score || report.grade || 'N/A';
console.log('Security score:', score);
document.getElementById('security-score').textContent = `Score: ${score}`;

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

{
  "status": 404,
  "error": "Not Found"
}
