## 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

## Broken Link Checker & Bulk URL Status Checker

Crawl a website and test every internal and external link, or bulk-check a list of URLs. Returns HTTP status, redirect chain, final URL, response time and which pages contain each broken link. Output only broken links to pay only for problems.

### Why this actor

- Two modes in one tool, 'foundOn' pages for each broken link, and an onlyBroken switch that makes clean sites nearly free.
- Pay only for results: **$1.00 per 1,000 link checkeds**, no start fee, failed lookups are free.
- Robust: automatic retries with exponential backoff, respects `Retry-After`, per-item error rows instead of crashed runs.
- Clean, flat JSON/CSV/Excel output ready for Google Sheets, Make, Zapier, n8n, Clay, or the Apify API.

### Use cases

- SEO site audits and link-rot cleanup
- Monitoring docs/marketing sites on a schedule
- Validating URL lists before email campaigns or migrations
- Checking redirect chains after a domain move

### Input

| Field | Type | Description |
|---|---|---|
| `urls` | array | check mode: list of URLs to status-check. crawl mode: website(s) to crawl for broken links. |
| `mode` | string | Bulk status check, or crawl a website and test every link on it. |
| `maxPages` | integer | Pages crawled per site. |
| `checkExternal` | boolean | Also test outbound links. |
| `onlyBroken` | boolean | Output only 4xx/5xx/timeouts (you are charged only for output rows). |
| `concurrency` | integer | Parallel requests. |
| `maxItems` | integer | 0 = no limit. |

Example input:

```json
{
  "urls": [
    "https://books.toscrape.com"
  ],
  "mode": "crawl",
  "maxPages": 4
}
```

### Output

Each dataset item looks like this (real sample from a test run, long fields trimmed):

```json
{
  "url": "https://html5shim.googlecode.com/svn/trunk/html5.js",
  "statusCode": 404,
  "ok": false,
  "finalUrl": "https://html5shim.googlecode.com/svn/trunk/html5.js",
  "redirectCount": 0,
  "redirectChain": null,
  "contentType": "text/html; charset=UTF-8",
  "responseTimeMs": 339,
  "internal": false,
  "foundOn": [
    "https://books.toscrape.com",
    "https://books.toscrape.com/catalogue/category/books/travel_2/index.html",
    "https://books.toscrape.com/catalogue/category/books_1/index.html",
    "\u2026"
  ],
  "foundOnCount": 4,
  "site": "https://books.toscrape.com",
  "scrapedAt": "2026-10-14T05:57:17+00:00"
}
```

Rows that could not be processed contain an `error` field and are **not charged**.

### Pricing

Pay-per-event: **$0.001** per link checked (= $1.00 / 1,000). Use **Max results** to cap spend. Apify's free plan credit covers thousands of results per month.

### Integrations & API

Run on a schedule in Apify Console, call via the Apify API / Python & JS clients, or connect to Make, Zapier, n8n, Google Sheets, Slack and webhooks. Works as a tool for AI agents via Apify MCP.

### FAQ

**Is it legal?** The actor only reads publicly available data from public endpoints, without logins, and does not bypass paywalls or access controls. You are responsible for using the data in line with applicable laws (e.g. GDPR) and the source sites' terms.

**Something broke?** Open an issue in the Issues tab; we typically respond within 24 hours and ship fixes fast.

# 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("shawndunn/broken-link-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);
});

from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.

# Prepare the Actor input
run_input = { "urls": ["https://apify.com"] }

# Run the Actor and wait for it to finish
run = client.actor("shawndunn/broken-link-checker").call(run_input=run_input)

## CLI example

```bash
echo '{
  "urls": [
    "https://apify.com"
  ]
}' |
apify call shawndunn/broken-link-checker --silent --output-dataset

```

## MCP server setup

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