## 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

## 🌐 Website Status Checker

A fast, reliable, and scalable tool to check the status of multiple websites in seconds.\
Perfect for developers, businesses, and monitoring workflows.

***

### 🚀 Features

- ⚡ **Bulk URL Checking** – Test hundreds or thousands of URLs in one run
- 📊 **Accurate Status Detection** – Supports 2xx, 3xx, 4xx, 5xx responses
- ⏱ **Response Time Tracking** – Measure performance for each request
- 🔁 **Redirect Handling** – Captures final destination URLs
- ❌ **Error Handling** – Detects DNS errors, timeouts, and unreachable domains
- 🚀 **High Performance** – Optimized with concurrency & keep-alive connections

***

### 📥 Input

Provide a list of URLs:

{
"urls": \[
"https://google.com",
"https://github.com",
"https://example.com"
]
}

***

### 📤 Output

Each URL returns structured results:

{
"url": "https://google.com",
"status": 200,
"responseTimeMs": 150,
"isUp": true,
"finalUrl": "https://www.google.com/",
"error": null
}

***

### 📌 Output Fields Explained

- **url** → Original URL provided
- **status** → HTTP status code
- **responseTimeMs** → Time taken to respond (milliseconds)
- **isUp** → true if status is 2xx or 3xx
- **finalUrl** → Final URL after redirects
- **error** → Error message if request failed

***

### 🧠 How It Works

- Sends HTTP requests to all URLs
- Measures response time
- Follows redirects automatically
- Marks URLs as **UP** or **DOWN**
- Captures failures without stopping the run

***

### ⚡ Performance

- Handles large batches efficiently
- Uses connection reuse (keep-alive)
- Optimized concurrency for fast execution

***

### 🎯 Use Cases

- Website uptime monitoring
- SEO audits & link validation
- API endpoint health checks
- Bulk URL verification
- Automation workflows (Make, Zapier, n8n)

***

### 🔒 Reliability

- Gracefully handles:
  - Invalid domains
  - Network errors
  - Timeouts
- Never crashes your run

***

### 💡 Tips

- Use valid URLs with http:// or https://
- Avoid sending too many requests to rate-limited servers

***

### 📈 Example Use Case

Check 1000 URLs in seconds and instantly identify:

- Broken links (404)
- Server issues (500)
- Slow websites

***

### 🏁 Summary

This actor provides a **simple, powerful, and scalable solution** to monitor website health with clean, structured output ready for automation, reporting, or integration.

# 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 = {
    "urls": [
        "https://apify.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("seeb/website-status-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 = { "urls": ["https://apify.com"] }

# Run the Actor and wait for it to finish
run = client.actor("seeb/website-status-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 '{
  "urls": [
    "https://apify.com"
  ]
}' |
apify call seeb/website-status-checker --silent --output-dataset

```

## MCP server setup

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