## 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 VAT Status Monitor (Supplier Watchdog, VIES)

Checks a company list against VIES, the EU's official VAT registry, and outputs the rows that changed since your last run.

A supplier's VAT turning invalid can void your input-VAT deduction on their invoices. It is also an early public sign of deregistration. The VIES website checks one number per page load. This actor stores each result in your Apify account and compares against it on every run.

### What a run returns

| changeType | Meaning |
|---|---|
| `BECAME_INVALID` | A VAT that was valid last run is now invalid |
| `BECAME_VALID` | An invalid VAT is now valid |
| `NAME_CHANGED` | The registered name in VIES changed |
| `ADDRESS_CHANGED` | The registered address in VIES changed |
| `NEW_VALID` / `NEW_INVALID` | First check of a company on this watchlist |
| `REGISTRY_UNAVAILABLE` | The member state registry was down. Your stored history stays as it was |
| `UNCHANGED` | Hidden by default. Set `fullReport` to true to see these rows |

### Setup

1. Paste your list. VAT numbers work directly. A domain also works, since the actor reads the company's legal page once, finds the VAT number there and stores it for later runs.
2. Create a schedule in Apify (daily or weekly).
3. Optional: set `webhookUrl`. When a watched VAT becomes invalid, the actor sends one POST containing the affected companies. Zapier, Make, n8n and Slack incoming webhooks accept this format.

```json
{
  "companies": [
    { "vat": "IE6388047V", "label": "Google Ireland" },
    { "domain": "acme.de", "label": "Acme GmbH" }
  ],
  "monitorId": "suppliers",
  "webhookUrl": "https://hooks.zapier.com/..."
}
```

Runs that share a `monitorId` compare against each other. A second id keeps a second list separate, for example "customers".

### Output example

```json
{
  "label": "Acme GmbH", "vatNumber": "DE123456789", "country": "DE",
  "changeType": "BECAME_INVALID", "vatValid": false,
  "previous": { "vatValid": true, "officialName": "ACME GMBH", "checkedAt": "2026-07-12T06:00:00Z" },
  "viesStatus": "OK", "checkedAt": "2026-07-19T06:00:00Z"
}
```

### Pricing

$0.004 per company checked. $0.02 per detected change. $0.005 at actor start. A weekly run over 200 suppliers with no changes costs $0.81.

### Reliability

Registry downtime and junk input come back as status codes and the run continues to the end. In live testing, a run over a list containing one malformed VAT number finished in 10 seconds with that row marked and the rest verified. A VIES outage leaves your stored history untouched until the registry answers again.

Data sources are the public VIES registry and public company webpages, with no login anywhere.

Built on the same verification core as [EU Company Enrichment with Official VAT Verification](https://apify.com/maatdata/eu-company-enrichment-vat-verified).

## `mode` (type: `string`):

CHECK mode runs a one-time audit batch. MONITOR mode updates stateful watchlists.

## `companies` (type: `array`):

List of companies or VAT numbers to check (1 to 250 items).

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

Name of the named state watchlist (1–40 alphanumeric characters). Required for MONITOR mode.
