README
Password Breach Checker tells you whether a password appears in the Pwned Passwords corpus of passwords exposed in data breaches. Send the password or its SHA-1 hash and get a breached flag. Paid plans add how many times it was seen and a risk level.
The Password Breach Checker API provides a simple, reliable way to integrate password breach checker functionality into your applications. Built for developers who need production-ready password breach checker capabilities without the complexity of building from scratch.
Quick Start
Using JavaScript
async function callPasswordBreachCheckerAPI() { try { const requestBody = { "password": "password123" }; const response = await fetch('https://api.apiverve.com/v1/passwordbreach', { method: 'POST', headers: { 'x-api-key': 'YOUR_API_KEY_HERE', 'Content-Type': 'application/json' }, body: JSON.stringify(requestBody) }); const data = await response.json(); console.log(data); } catch (error) { console.error('Error:', error); } } callPasswordBreachCheckerAPI();
Using cURL
curl -X POST "https://api.apiverve.com/v1/passwordbreach" \ -H "x-api-key: YOUR_API_KEY_HERE" \ -H "Content-Type: application/json" \ -d '{ "password": "password123" }'
