# EU VAT Status Monitor (Supplier Watchdog, VIES) (`apixyz/eu-vat-status-monitor`) Actor Checks your supplier list against VIES, the EU's official VAT registry, on a schedule you set. Remembers each company's last result and outputs the rows that changed. A VAT turning invalid can send a webhook to Zapier, Make or Slack. $0.004 per check, $0.02 per detected change. - **URL**: https://apify.com/apixyz/eu-vat-status-monitor.md - **Developed by:** [Tarek Etman](https://apify.com/apixyz) (community) - **Categories:** Automation, Integrations, Lead generation - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing from $4.00 / 1,000 company checked (vies)s This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. 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. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # 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). *Built by MaatData.* # Actor input Schema ## `companies` (type: `array`): Suppliers/customers to monitor. Each item: {"vat": "IE6388047V", "label": "Acme Ltd"} or {"domain": "acme.de"}. Labels are echoed in alerts. ## `monitorId` (type: `string`): Name of this watchlist. Runs with the same name compare against each other. Use different names for different lists (e.g. 'suppliers', 'customers'). ## `fullReport` (type: `boolean`): Output every company each run. Off (default) = output only changes — ideal for scheduled runs. ## `webhookUrl` (type: `string`): Optional. POSTed when any watched VAT becomes invalid. Works with Zapier/Make/n8n/Slack incoming webhooks. ## `maxConcurrency` (type: `integer`): Parallel lookups. Keep moderate to respect VIES. ## Actor input object example ```json { "companies": [ { "vat": "IE6388047V", "label": "Google Ireland" }, { "vat": "FR40303265045", "label": "Sodimas" } ], "monitorId": "default", "fullReport": false, "maxConcurrency": 4 } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "companies": [ { "vat": "IE6388047V", "label": "Google Ireland" }, { "vat": "FR40303265045", "label": "Sodimas" } ] }; // Run the Actor and wait for it to finish const run = await client.actor("apixyz/eu-vat-status-monitor").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
