## 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

**Facebook Account Checker** takes a list of phone numbers and tells you, for each one, whether a **Facebook account exists** for that number — no login, no friend requests, no ban risk.

### What does Facebook Account Checker do?

Give it phone numbers in international format and it returns, per number, whether a [Facebook](https://www.facebook.com) account is registered to it. Run it on the [Apify platform](https://apify.com) for API access, scheduling, integrations, automatic proxy rotation, and run monitoring.

### Why use Facebook Account Checker?

- **Lead qualification** — see which contacts are reachable on Facebook.
- **List hygiene** — flag numbers with no social presence before a campaign.
- **Audience research** — measure Facebook coverage across a phone list.
- **Bulk, structured output** — one row per number, ready to export.

### How to use Facebook Account Checker

1. Open the **Input** tab.
2. Paste your phone numbers into **Phone Numbers** (international format, e.g. `+15551234567`).
3. Keep **Proxy** on Apify Residential for best reliability.
4. Click **Start** and read the results in the **Output** tab.

### Input

| Field | Type | Description |
|---|---|---|
| `phone_numbers` | array | Numbers to check, international format. Max 100 per run. |
| `proxy_configuration` | object | Proxy settings. Residential recommended. |

```json
{
    "phone_numbers": ["+15551234567", "+447700900123"],
    "proxy_configuration": { "useApifyProxy": true, "apifyProxyGroups": ["RESIDENTIAL"] }
}
```

### Output

One row per number. You can download the dataset in various formats such as JSON, HTML, CSV, or Excel.

```json
{
    "phone_number": "+15551234567",
    "on_facebook": true,
    "success": true,
    "error": null
}
```

### Data table

| Field | Meaning |
|---|---|
| `phone_number` | The number checked, normalized to international format. |
| `on_facebook` | `true` if a Facebook account exists for this number, `false` if not. |
| `success` | `true` when the check completed; `false` if it could not be resolved. |
| `error` | Reason a row could not be checked (invalid format, temporary block, etc.). |

### How much does it cost?

Checks are lightweight — most runs cost a fraction of a cent per number in platform compute. Batch numbers into a single run to minimize overhead.

### Tips

- Feed numbers in bulk rather than one run per number.
- Keep the residential proxy enabled for large lists to avoid temporary blocks.
- Schedule recurring runs to keep a contact list continuously validated.

### FAQ & support

- **Is this legal?** The Actor only reads publicly observable account-existence signals and never logs in. You are responsible for complying with applicable laws and Facebook's terms when processing personal data.
- **Why is a row errored?** The number was malformed or the check was temporarily blocked — check the `error` column and retry.
- **Found a bug or need a custom version?** Open an issue on the Actor's **Issues** tab.

# 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 = {
    "phone_numbers": [
        "+15551234567",
        "+447700900123"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("maged120/facebook-phone-number-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);
});

# 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():

## CLI example

```bash
echo '{
  "phone_numbers": [
    "+15551234567",
    "+447700900123"
  ]
}' |
apify call maged120/facebook-phone-number-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,maged120/facebook-phone-number-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).
