# Find broken links and 404s on a website (demo site)

**Use case:** 

Crawls up to 15 pages of crawler-test.com, a public site built for testing crawlers, and lists every broken link, 404, server error, broken image and long redirect chain with the page and anchor text where it appears. Replace the start URL with your own site to audit it.

## Input

```json
{
  "startUrls": [
    {
      "url": "https://crawler-test.com/"
    }
  ],
  "maxPages": 15,
  "maxDepth": 10,
  "checkExternalLinks": true,
  "checkImages": true,
  "redirectChainThreshold": 1,
  "reportRedirects": true,
  "includeOkLinks": false,
  "maxConcurrency": 8,
  "respectRobotsTxt": true
}
```

## Output

    "label": "Severity"
  },
  "issue": {
    "label": "Issue"
  },

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/batreek/broken-link-checker.md

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`).
