# EU Company Change Monitor EXPERT (`reapx/eu-company-change-monitor`) Actor

Watches a list of EU company domains on a schedule. Reads each company's imprint or legal page and reports changes to the VAT number, legal name, registered address, contact emails, and detected site technology. A failed fetch keeps stored history intact. From $0.006 per company checked.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **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).

For usage examples, see the [API](#api) section below.

# README

## EU Company Change Monitor

Watches a list of company domains and reports changes to what those companies publish about themselves. Each run reads the company's imprint or legal page, compares it with the stored result under your `monitorId`, and outputs only the rows that changed.

A changed VAT number on a supplier invoice can cost you the input-VAT deduction. Outdated registered addresses invalidate contract records. This actor reports both on the next scheduled run after the company's own page shows them.

### What a run returns

| `changeType` | Meaning |
|---|---|
| `BASELINE` | First reliable inspection of a domain on this watchlist |
| `VAT_CHANGED` | The VAT number published on the legal page changed |
| `LEGAL_NAME_CHANGED` | The published legal name changed |
| `ADDRESS_CHANGED` | The published registered address changed |
| `CONTACT_CHANGED` | Public contact emails changed |
| `TECH_ADDED` / `TECH_REMOVED` | Detected site technology changed |
| `PAGE_UNREACHABLE` | The page could not be read. Stored history stays intact |
| `UNCHANGED` | Hidden by default. Set `fullReport` to true to include these |

Rows with several simultaneous changes carry one primary `changeType` plus a `changes` array with every field delta, previous and current values included.

### Input

```json
{
  "domains": [
    { "domain": "sap.com", "label": "SAP" },
    { "domain": "zalando.de", "label": "Zalando" }
  ],
  "monitorId": "suppliers",
  "webhookUrl": "https://hooks.zapier.com/..."
}
```

Runs sharing a `monitorId` compare against each other. The optional HTTPS webhook receives one POST per run when change rows exist. VIES re-verification of found VAT numbers is available with `verifyVatWithVies` and is off by default.

### How pages are found

The actor reads the homepage, follows the highest-ranked legal-page link (Impressum, legal notice, mentions légales and equivalents in six languages), and also tries the well-known paths EU companies conventionally use, such as `/impressum` and `/legal-notice`. In live testing this resolved the correct imprint for sap.com and zalando.de and extracted their registered VAT numbers.

### Limits stated plainly

Fields published as labeled text extract best. Legal names and addresses written as unlabeled prose can come back empty while the VAT number and contact emails still fill. A site that refuses datacenter traffic returns `PAGE_UNREACHABLE` and keeps its stored history; the proxy input accepts Apify Proxy settings including residential groups.

### Pricing

$0.006 per company checked, $0.025 per change detected, $0.005 at actor start. A weekly watch on 100 suppliers runs about $0.61 per run, or roughly $2.65 per month at that cadence, before any change events.

### Related actors

Verify a company list against the official VIES registry with [EU Company Enrichment](https://apify.com/maatdata/eu-company-enrichment-vat-verified). Watch the VAT number's registry validity itself with [EU VAT Status Monitor](https://apify.com/maatdata/eu-vat-status-monitor); it queries VIES while this actor reads the company's own website.

# Actor input Schema

## `domains` (type: `array`):

Company websites to monitor. Each item needs a domain; the label is echoed back in output rows for your own reference.

## `monitorId` (type: `string`):

Runs with the same name share saved history.

## `fullReport` (type: `boolean`):

Include unchanged domains in the dataset.

## `webhookUrl` (type: `string`):

Receives one POST when a run detects company detail changes.

## `verifyVatWithVies` (type: `boolean`):

Check an extracted VAT number against VIES during this run.

## `maxConcurrency` (type: `integer`):

Number of domains fetched at the same time.

## `proxy` (type: `object`):

Optional Apify Proxy settings used after a direct request fails.
