# Export Sitemap URLs with Last Modified Dates

**Use case:** 

Give one or more sitemap URLs and export unique page URLs with lastmod, source sitemap and observation time. Keep the SNAPSHOT output for later comparisons. The supplied 84-URL example costs $0.043; pricing is $0.001 start + $0.0005 per emitted URL, platform usage included.

## Input

```json
{
  "sitemapUrls": [
    "https://www.sitemaps.org/sitemap.xml"
  ],
  "maxUrls": 100,
  "maxSitemaps": 5,
  "urlContains": ""
}
```

## Output

```json
{
  "url": {
    "label": "URL",
    "format": "string"
  },
  "change": {
    "label": "Change",
    "format": "string"
  },
  "lastmod": {
    "label": "Last modified",
    "format": "string"
  },
  "sourceSitemap": {
    "label": "Source sitemap",
    "format": "string"
  },
  "observedAt": {
    "label": "Observed at",
    "format": "string"
  }
}
```

## 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/gertner-data/sitemap-delta.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`).
