## 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

## WLW Scraper - B2B Companies & Contacts (DACH)

> **Disclaimer:** Unofficial integration for publicly accessible sources. Trademarks belong to their respective owners. Provided for informational use only; users must comply with applicable platform terms and laws.

> **Crawloop Visable B2B Directory Suite** — structured company profiles from WLW (DACH) and Europages (Europe-wide).

| WLW (DACH) | Europages (Europe) |
| :--- | :--- |
| **WLW Scraper** ◄── you are here | [Europages Scraper](https://apify.com/crawloop/europages-scraper) |
| DE / AT / CH suppliers, phone, email, VAT, contacts | Multi-country EU directory, VAT, contacts, certificates |

**WLW scraper** for Apify — extract **DACH B2B company profiles** from Wer liefert was (Germany, Austria, Switzerland) into clean JSON. Collect **manufacturers, distributors, wholesalers and service providers** with **phone, email, VAT ID, street address, GPS coordinates, certificates**, named **contact persons**, and optional **product catalog cards**.

Ideal for **supplier sourcing**, **sales prospecting**, **CRM enrichment**, and **firmographic research** across the German-speaking market. Fast HTTP crawl: listing pages via Nuxt SSR, company details via lightweight `_payload.json` — no headless browser.

### Use cases

| Use case | What you get |
| :--- | :--- |
| **Find DACH suppliers** | Keyword / category listings with company id, city, country, website |
| **Lead & contact lists** | Phone, email, and named managers from company profiles |
| **Firmographics & compliance** | VAT ID, founding year, employee range, certificates |
| **Geo & territory mapping** | Street address plus latitude / longitude |
| **Product landscape** | Optional product cards from each company catalog |
| **Multi-market runs** | Switch host between DE / AT / CH |

### When to use this Actor

- You need **WLW B2B company data** as structured dataset rows
- You want **keyword search** or paste **category / profile URLs**
- You prefer a **fast, browser-free** crawl on Apify

### When not to use this Actor

- **Guaranteed email on every profile** — many free listings publish phone and website only
- **Authenticated / gated WLW fields** — public SSR / payload only
- **Sending RFQs** through the WLW contact form — this Actor is read-only extraction
- **Non-WLW directories** — use a source-specific Actor instead

### Key features

- **Keyword search** — builds WLW SEO listing URLs (`/de/suche/…`)
- **Category & start URLs** — paste listing pages or company profile links
- **DACH markets** — `de` (wlw.de), `at` (wlw.at), `ch` (wlw.ch)
- **Detail enrichment** — `fetchDetails` loads company `_payload.json` for VAT, contacts, certificates, geo
- **Optional products** — `includeProducts` attaches catalog cards from the profile
- **Streaming results** — dataset rows appear while the run is in progress
- **Pagination controls** — `maxPages` + `maxItems` for predictable run size
- **Lightweight & resilient** — `curl_cffi` Chrome TLS fingerprinting, proxy session rotation on challenges

### Input parameters

| Parameter | Type | Default | Description |
| :--- | :--- | :--- | :--- |
| `searchKeywords` | Array | `["maschinenbau"]` | Keywords → WLW listing URLs. |
| `categoryUrls` | Array | `[]` | Direct listing / category URLs. |
| `startUrls` | Array | `[]` | Company profiles and/or extra listings. |
| `market` | String | `"de"` | DACH host: `de`, `at`, or `ch`. |

| `includeProducts` | Boolean | `false` | Attach product cards from profiles. |
| `maxItems` | Integer | `50` | Max dataset rows (`0` = unlimited within `maxPages`). |
| `maxPages` | Integer | `3` | Max listing pages per list URL. |
| `concurrency` | Integer | `6` | Parallel detail workers (1–15; lower if challenges). |
| `proxyConfiguration` | Object | residential | Apify Proxy settings (residential recommended). |

#### Example — German timber-machine suppliers

```json
{
  "searchKeywords": ["abbundmaschinen"],
  "market": "de",
  "language": "de",
  "fetchDetails": true,
  "includeProducts": false,
  "maxItems": 100,
  "maxPages": 5,
  "concurrency": 6,
  "proxyConfiguration": {
    "useApifyProxy": true,
    "apifyProxyGroups": ["RESIDENTIAL"]
  }
}
```

#### Example — Direct company profiles + category URL

```json
{
  "categoryUrls": [
    { "url": "https://www.wlw.de/de/suche/abbundmaschinen" }
  ],
  "startUrls": [
    { "url": "https://www.wlw.de/de/firma/mustertechnik-gmbh-100001" }
  ],
  "market": "de",
  "fetchDetails": true,
  "maxItems": 50,
  "maxPages": 2,
  "concurrency": 4
}
```

### Output

Each dataset item is one WLW company. Example fields (fictional sample for illustration):

```json
{
  "recordType": "company",
  "companyId": "100001",
  "uuid": "00000000-0000-4000-8000-000000000001",
  "name": "Mustertechnik GmbH",
  "slug": "mustertechnik-gmbh-100001",
  "market": "de",
  "language": "de",
  "url": "https://www.wlw.de/de/firma/mustertechnik-gmbh-100001",
  "description": "Example industrial supplier description for documentation only.",
  "websiteUrl": "https://www.mustertechnik.example/",
  "email": "info@mustertechnik.example",
  "phoneNumber": "+493012345678",
  "businessTypes": ["distribution"],
  "city": "Berlin",
  "countryCode": "DE",
  "address": {
    "street": "Musterstrasse 1",
    "zipcode": "10115",
    "city": "Berlin",
    "countryCode": "DE",
    "latitude": 52.52,
    "longitude": 13.405
  },
  "foundingYear": 1998,
  "employeeCount": "20-49",
  "vatId": "DE000000000",
  "distributionArea": "national",
  "contactPersons": [
    {
      "firstName": "Max",
      "lastName": "Mustermann",
      "email": "max.mustermann@mustertechnik.example",
      "phoneNumber": "+493012345679",
      "executiveType": "executive"
    }
  ],
  "logoUrl": "https://cdn.example.com/logos/mustertechnik.png"
}
```

### Workflow

1. Build listing URLs from `searchKeywords`, `categoryUrls`, and/or `startUrls`
2. Paginate WLW search pages and parse Nuxt `__NUXT_DATA__` company rows
3. Deduplicate by `companyId` / `uuid`
4. Optionally enrich each profile via `/firma/{slug}/_payload.json`
5. Stream rows to the default dataset (PPE event `scraped-company`)

### Tips for better results

- Prefer **residential proxy** for larger crawls; lower `concurrency` (3–5) if you see challenges
- Set `fetchDetails: false` for a fast listing-only pass, then re-run with profile URLs for enrichment
- Use `market` to target Austria (`at`) or Switzerland (`ch`) hosts
- Keep `includeProducts` off unless you need catalog cards (larger payloads)
- Need **pan-European** supplier coverage beyond DACH? Use [Europages Scraper](https://apify.com/crawloop/europages-scraper)
