## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

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 examples already wired to this Actor's own input schema, see the [API](#api) section below.

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`).

# README

## Finnish Company Events Feed — PRH / YTJ Open Data API (`itulo/prh-company-events`)

Track daily **Finnish Trade Register (Kaupparekisteri / YTJ)** company events and monitor Finnish Business IDs (`Y-tunnus`) using the official **Finnish Patent and Registration Office (PRH) Open Data v3 APIs** (`avoindata.prh.fi`). Built for Nordic B2B KYB onboarding, credit risk alerts, supplier monitoring, and CRM enrichment.

Ships as both a **Pay-Per-Event Apify Actor** (`itulo/prh-company-events`) and an open-source **stdio MCP Server** (`src/mcp-server.js`).

> **Independent Tool Notice:** Not affiliated with or endorsed by PRH (Patentti- ja rekisterihallitus) or YTJ. Uses no PRH or YTJ logos or look-alike UI.

***

### Supported Finnish Company Event Types & Watchlist Mode

- **Daily Trade Register Events (`eventTypes`):**
  - `new_company` — Newly registered Finnish companies (`Oy`, `Oyj`, `Ky`, `Ay`, cooperatives)
  - `name_change` — Company name changes (includes `previousName`)
  - `liquidation` & `bankruptcy` — Corporate insolvency, liquidation (`selvitystila`), and bankruptcy (`konkurssi`) filings
  - `restructuring`, `dissolution`, `merger_demerger`, `industry_change` (TOL 2008), `domicile_change`, `articles_change`
- **Business ID Watchlist Diffs (`watchBusinessIds`):** Track a portfolio of Finnish Business IDs (`Y-tunnus`) across runs and detect changes to company name, TOL 2008 main business line, company form, liquidation/bankruptcy status, or municipality.
- **Strict GDPR Company-Level Whitelist:** Strips `c/o` names, street addresses, PO boxes, and natural-person board/signatory entry codes. Retains only postcode, city, municipality code, and a boolean `includesRepresentationChanges` flag.

### Connect to Claude Desktop, Cursor & MCP Clients (Model Context Protocol)

You can use **`itulo/prh-company-events`** as a live tool inside **Claude Desktop**, **Cursor**, **Windsurf**, or any MCP-compatible AI agent in two ways:

#### Option A: Hosted Apify MCP Server (`@apify/actors-mcp-server`)

Zero local setup required. Add this to your `claude_desktop_config.json` (macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`, Windows: `%APPDATA%\Claude\claude_desktop_config.json`) or Cursor `.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "prh-company-events": {
      "command": "npx",
      "args": [
        "-y",
        "@apify/actors-mcp-server",
        "--actors",
        "itulo/prh-company-events"
      ],
      "env": {
        "APIFY_TOKEN": "YOUR_APIFY_API_TOKEN"
      }
    }
  }
}
```

#### Option B: Local Stdio MCP Server (Open-Source CLI)

Run the bundled stdio MCP server (`src/mcp-server.js`) directly on your machine. Exposed MCP tools: `prh_company_events`, `prh_watch_companies`, `prh_licence_info`.

```json
{
  "mcpServers": {
    "prh-company-events-local": {
      "command": "node",
      "args": [
        "/absolute/path/to/tools/prh-company-events/src/mcp-server.js"
      ]
    }
  }
}
```

***

### n8n, Make.com & REST API Integration (One-Call Sync JSON)

Trigger **`itulo/prh-company-events`** synchronously and get the normalized JSON dataset items back in a single HTTP request — ideal for **n8n `HTTP Request` nodes**, **Make.com**, **Zapier**, or cron webhooks:

- **Method:** `POST`
- **Endpoint:** `https://api.apify.com/v2/acts/itulo~prh-company-events/run-sync-get-dataset-items?token=YOUR_APIFY_API_TOKEN`
- **Headers:** `Content-Type: application/json`

#### cURL Example

```bash
curl -s -X POST \
  "https://api.apify.com/v2/acts/itulo~prh-company-events/run-sync-get-dataset-items?token=${APIFY_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"eventTypes":["new_company","name_change","liquidation","bankruptcy"],"dateFrom":"2026-10-20","dateTo":"2026-10-27","maxPerEvent":10,"alertMode":false}'
```

### Frequently Asked Questions (FAQ)

#### Which official Finnish Trade Register APIs does this actor query?

It queries the official Finnish Patent and Registration Office (PRH / Patentti- ja rekisterihallitus) Open Data v3 endpoints: `opendata-ytj-api/v3` and `opendata-registerednotices-api/v3` (`avoindata.prh.fi`). No API key is required.

#### How does the Business ID (Y-tunnus) watchlist mode work?

Pass an array of Finnish Business IDs in `watchBusinessIds` (e.g. `["0112038-9", "0892215-7"]`). The actor snapshots each company’s registered name, TOL 2008 industry code, company form, liquidation/bankruptcy situation, and municipality in a named KV store and emits a diff whenever a tracked supplier or customer changes status.

#### How is GDPR compliance enforced on Finnish company records?

Every record passes through a strict company-level whitelist (`companyLevel()`). Street addresses, `c/o` personal names, building/apartment numbers, and person-level Trade Register entry codes (board members, managing directors, auditors, beneficial owners) are stripped; only postcode, city, municipality code, and a boolean `includesRepresentationChanges` flag are retained.

## CLI example

```bash
echo '{}' |
apify call itulo/prh-company-events --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,itulo/prh-company-events"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
