# Monitor Websites For Contact Changes

**Use case:** 

Watches a set of sites and writes only the ones whose contacts moved - a new address, a number that disappeared, a social profile added. Nothing changed means an empty dataset and no charge, and the log says so in plain words. The memory survives between runs.

## About this Actor

This example demonstrates how to use [Impressum & Imprint Contact Scraper - Emails, Phones, Socials](https://apify.com/snow_leo_data/website-contact-scraper.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/snow_leo_data/website-contact-scraper.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`).
