# Audit old links to shut-down platforms for silent link rot

**Use case:** 

Links to platforms that shut down often keep returning HTTP 200 while redirecting to a generic homepage, so a plain 'is it up' check says they're fine.

## Input

```json
{
  "items": [
    "https://answers.yahoo.com/question/index?qid=20080101000000AAxyz12",
    "https://answers.yahoo.com/question/index?qid=20130101000000AAqwe12",
    "https://answers.yahoo.com/question/index?qid=20111111111111AAzxc34"
  ],
  "maxConcurrency": 5,
  "proxyConfiguration": {
    "useApifyProxy": true
  }
}
```

## Output

```json
{
  "data.requestedUrl": {
    "label": "URL checked",
    "format": "text"
  },

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

- **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).
