# Find New Blog Posts on Any Website from Its Sitemap

**Use case:** 

Track the blog posts a website publishes, straight from its XML sitemap: page URL, lastmod date and sitemap, one row per post. It finds the sitemaps from robots.txt, keeps only URLs matching */blog/* and, with Only new URLs on, returns just the posts added since your last run. Put in a competitor's site and schedule it daily for a cheap new-post alert.

## Input

```json
{
  "startUrls": [
    "https://crawlee.dev"
  ],
  "keepItemFields": true,
  "includePatterns": [
    "*/blog/*"

  "sameDomainOnly": true,
  "onlyNew": true,
  "skipExistingOnFirstRun": false,
  "maxSitemaps": 500,
  "concurrency": 3,
  "maxResults": 100

## 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/charlesmarkette/sitemap-url-extractor-new-page-monitor.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`).
