## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## 🔐 Microsoft Account Checker (Outlook, Hotmail, Office 365, Live)

Validate and verify the existence of any email address against Microsoft's official Identity Provider (IdP) system instantly. Efficiently check Outlook, Hotmail, Office 365, Live, and custom domain Microsoft corporate/educational accounts.

No browsers, proxies, or complex browser automation scripts are needed. This Actor leverages a high-performance edge service that directly verifies registration status with Microsoft, yielding results in milliseconds.

***

### 🌟 Key Features

- **High-Speed Account Verification**: Direct communication with Microsoft Identity Provider endpoints provides lightning-fast checks.
- **Bulk Check Ready**: Lightweight execution with minimal overhead, suitable for large lists of accounts.
- **Identify Account Status**: Returns clear, structured responses mapping whether the account exists and the associated account type.
- **CORS-Enabled Routing**: Secured via custom `X-Api-Key` headers for seamless application programming.
- **Zero Blocks or Captchas**: Uses optimized browser header profiles to mimic real user interactions, preventing rate limiting and IP blocks.

***

### 🛠️ How It Works

This actor queries an edge-deployed Cloudflare Worker gateway, which acts as a secure reverse-proxy. The gateway forwards an inquiry to Microsoft's official discovery endpoints (`odc.officeapps.live.com`). It reads the authentication responses, parses the underlying IdP tags, and converts the results into a standardized format.

- **Registered Personal Account**: Returns `Microsoft Account` (is\_registered = true).
- **Work or School Directory**: Identifies organization-managed profiles.
- **Not Registered**: Identifies if the email address is completely unregistered with Microsoft services (is\_registered = false).

***

### 📥 Input Parameters

| Field | Type | Description | Prefill Example |
| :--- | :--- | :--- | :--- |
| **Email Address** | `string` | The target email address to verify. | `test@outlook.com` |

#### Input JSON Example

```json
{
  "email": "test@outlook.com"
}
```

***

### 📤 Output Data Structure

Tabular datasets output clean rows mapping the account info:

#### Output JSON Example

```json
{
  "success": true,
  "email_tested": "test@outlook.com",
  "is_registered": true,
  "status": "Microsoft Account",
  "description": "Successfully verified account status."
}
```

### 💳 Monetization & Cost

This Actor utilizes the **Pay-Per-Event (PPE)** pricing model on the Apify Store:

- **Base Pricing**: Only **$1.00 per 1,000 successful lookups** (`$0.001` per event).
- **Pay as You Go**: If validation fails due to network/gateway issues, no billing charges occur.

# Actor input Schema

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "email": "test@outlook.com"
};

// Run the Actor and wait for it to finish
const run = await client.actor("dev00/microsoft-account-checker").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "email": "test@outlook.com" }

# Run the Actor and wait for it to finish
run = client.actor("dev00/microsoft-account-checker").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "email": "test@outlook.com"
}' |
apify call dev00/microsoft-account-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,dev00/microsoft-account-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).
