## 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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Website Uptime & Status Checker

**Is your website up? Check HTTP status, response time, SSL and server info for any URL — no API key, no login.**

This Apify Actor takes a list of URLs and returns a live status snapshot for each one: whether it is **up or down**, the **HTTP status code**, **response time in milliseconds**, the **final URL after redirects**, the **server** and **content-type** headers, and whether **SSL** is reachable. Perfect for uptime monitoring, site health dashboards, SLA checks and QA smoke tests.

Requests use a real Chrome browser fingerprint (via `curl_cffi`), so sites that block plain bots still respond, with a plain `urllib` fallback for maximum reliability.

---

### Features

- ✅ **Up/down classification** — a URL is *up* on any `2xx`/`3xx` status
- ⏱️ **Response time** measured in milliseconds
- 🔁 **Redirect tracking** — final URL and a `redirected` flag
- 🔒 **SSL check** — is the site reachable over HTTPS without error
- 🖥️ **Server & content headers** — `Server`, `Content-Type`, `Content-Length`
- 🧵 **Concurrent** — checks many URLs in parallel
- 🔑 **No API key, no login** — just paste URLs

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `mode` | select | `check` | `check` returns a status snapshot per URL |
| `urls` | array | `["https://github.com","https://example.com"]` | URLs to check (bare domains auto-prefixed with `https://`) |
| `timeoutSec` | integer | `15` | Max seconds to wait per URL |
| `maxItems` | integer | `200` | Cap on URLs processed per run (max 2000) |

#### Example input

```json
{
  "mode": "check",
  "urls": ["https://github.com", "https://example.com"],
  "timeoutSec": 15,
  "maxItems": 200
}
````

### Output

One dataset item per URL:

```json
{
  "url": "https://github.com",
  "up": true,
  "status_code": 200,
  "response_time_ms": 1040,
  "final_url": "https://github.com/",
  "redirected": false,
  "server": "github.com",
  "content_type": "text/html; charset=utf-8",
  "content_length": null,
  "ssl_valid": true,
  "error": null,
  "checked_at": "2026-07-24T10:00:00+00:00",
  "source": "uptime-monitor",
  "scraped_at": "2026-07-24T10:00:00+00:00"
}
```

All fields are nullable. A failed request still emits a row with `up: false` and a human-readable `error`.

### Use cases

- **Uptime monitoring** — schedule a run and alert when `up` flips to false
- **Site health** — spot slow response times and broken SSL at a glance
- **SLA checks** — record status and latency evidence over time
- **QA** — smoke-test a list of environments after every deploy

### Pricing

Runs on the smallest memory tier and is extremely cheap — roughly **$0.50 per 1,000 URLs checked**, depending on target response times. Only pay for what you check.

### FAQ

**Does it need an API key?** No. Paste URLs and run.

**What counts as "up"?** Any HTTP `2xx` or `3xx` response. `4xx`/`5xx` and connection failures are treated as down.

**Can I monitor on a schedule?** Yes — use Apify Schedules to run it every few minutes and connect a webhook/integration to alert on downtime.

# Actor input Schema

## `mode` (type: `string`):

What the actor does. 'check' takes your URLs and returns a live status snapshot (up/down, HTTP status, response time, SSL, server) for each one.

## `urls` (type: `array`):

One or more website URLs to check. A bare domain (example.com) is auto-prefixed with https://. Each URL yields exactly one result row.

## `timeoutSec` (type: `integer`):

Maximum seconds to wait for each URL before recording it as an error/down.

## `maxItems` (type: `integer`):

Safety cap on how many URLs are processed in one run. Extra URLs beyond this limit are ignored.

## Actor input object example

```json
{
  "mode": "check",
  "urls": [
    "https://github.com",
    "https://example.com"
  ],
  "timeoutSec": 15,
  "maxItems": 200
}
```
