## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## 🔓 Email Data Breach Checker — Find Out If Your Email Has Been Leaked

**The fastest and most affordable way to check if your email addresses have been exposed in data breaches. Scan one email or in bulk.**

> ✅ Best **"Have I Been Pwned" alternative** on Apify — with bulk scanning, risk scoring, and API access built in.

***

### Why You Need This Tool

Every day, millions of email addresses and passwords are leaked through data breaches. **You might be exposed right now without knowing it.**

- 🏢 **Companies** lose an average of **$4.45 million per data breach** (IBM, 2023)
- 📧 Over **12 billion accounts** have been leaked across known breaches
- 🔑 **65% of people** reuse passwords — one breach can compromise everything

Whether you're protecting yourself, your team, or your customers — you need to know **which emails are at risk and how badly**.

***

### What This Tool Does

Simply enter one or more email addresses, and get a **complete breach report** for each one:

| What You Get | Details |
|---|---|
| ✅ **Breach Status** | Instantly know if an email has been compromised |
| 🔢 **Breach Count** | Total number of breaches found for each email |
| 🌐 **Affected Sites** | Full list of breached sites (Canva, Duolingo, LinkedIn, etc.) |
| ⚠️ **Risk Score** | A 0–100 risk rating so you can prioritize action |
| 🏷️ **Risk Label** | Clear risk level: Low, Medium, High, or Critical |
| 📊 **Analytics** | Additional insights when available |
| ⏱️ **Timestamp** | Exact time of each check for audit trails |

#### 🏢 IT Managers & CISOs

Monitor your organization's email exposure across every known breach. Prioritize remediation with risk scores.

#### 🔍 Penetration Testers & OSINT Researchers

***

### How to Use It

#### Input

Just provide a list of email addresses:

```json
{
    "emails": [
        "your.email@gmail.com",
        "another.email@company.com",
        "third.email@yahoo.com"
    ]
}
```

That's it. **No configuration needed.** No API keys to set up. No complicated settings.

#### Output

For each email, you'll receive a detailed breach report:

```json
{
    "email": "your.email@gmail.com",
    "status": "breached",
    "breachCount": 32,
    "breachNames": ["Canva", "Duolingo", "LinkedIn", "..."],
    "breachSites": ["Canva", "Duolingo", "LinkedIn", "..."],
    "riskLabel": "Critical",
    "riskScore": 85,
    "pasteCount": 0,
    "analyticsAvailable": true,
    "checkedAt": "2026-03-10T14:09:12.592915+00:00"
}
```

#### Understanding Your Results

| Risk Score | Risk Label | What It Means |
|---|---|---|
| 0–20 | **Low** | Minimal exposure — keep monitoring |
| 21–50 | **Medium** | Some breaches found — change passwords on affected sites |
| 51–75 | **High** | Significant exposure — immediate password changes + enable 2FA |
| 76–100 | **Critical** | Severe risk — change all passwords, enable 2FA everywhere, monitor accounts |

### FAQ

#### Where does the breach data come from?

We aggregate data from known public breach databases, paste sites, and security research sources to give you the most comprehensive results.

#### Is this legal?

Yes. This tool checks publicly known breach data — the same way "Have I Been Pwned" and similar services work. No personal data is stored after the scan.

#### How often is the breach database updated?

The breach data sources are continuously updated as new breaches become publicly known.

#### Can I integrate this with my security tools?

Absolutely. Use the Apify API, webhooks, or connect via Zapier, Make, or n8n to push results into any SIEM, dashboard, or notification system.

## CLI example

```bash
echo '{
  "emails": [
    "breach-check-demo@example.com"
  ]
}' |
apify call lofomachines/email-breach-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,lofomachines/email-breach-checker"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
