# Track new and changed URLs in an XML sitemap

**Use case:** 

Compare the public sitemaps.org XML sitemap across runs, then replace it with your own document. Get current URLs, metadata edits and entries absent from the latest snapshot. $0.01 per complete document check, including unchanged checks; platform usage included. Maximum 5,000 entries and 2 MB per document. Absence does not prove page deletion; index children are not fetched automatically.

## Input

```json
{
  "urls": [
    "https://www.sitemaps.org/sitemap.xml"
  ],
  "monitorId": "sitemap-monitor",
  "firstRun": "emit"
}
```

## Output

```json
{
  "inputUrl": {
    "label": "inputUrl",
    "format": "string"
  },
  "documentType": {
    "label": "documentType",
    "format": "string"
  },
  "entryCount": {
    "label": "entryCount",
    "format": "integer"
  },
  "changeCount": {
    "label": "changeCount",
    "format": "integer"
  },
  "changes": {
    "label": "changes",
    "format": "array"
  }
}
```

## About this Actor

This example demonstrates how to use [Sitemap Delta Monitor | New & Changed URLs](https://apify.com/sbio-apps/sitemap-delta-monitor.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/sbio-apps/sitemap-delta-monitor.md) to learn more, explore other use cases, and run it yourself.


## 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).
