# RSS keyword alerts: only new posts that mention your topics

**Use case:** 

Only the new items whose title, summary or link mention Artemis or Mars come back, and only they are charged beside the run fee. Replace the words with your brand, competitors or topics and send each row to Slack or e-mail.

## Input

```json
{
  "sources": [
    "https://www.nasa.gov/feed/"
  ],
  "keywords": [
    "Artemis",
    "Mars"
  ],
  "monitorName": "nasa-keywords",
  "maxItemsPerSource": 20
}
```

## Output

```json
{
  "input": {
    "label": "Source",
    "format": "string"
  },
  "status": {
    "label": "Status",

## About this Actor

This example demonstrates how to use [RSS Feed & Sitemap Monitor — New Items Only](https://apify.com/victorix/rss-sitemap-monitor.md) with a specific input configuration.

## 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/victorix/rss-sitemap-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`).
