## 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

## WLW (Wer liefert was) B2B Suppliers & Email Enricher 🏭🇩🇪

High-speed, unblockable scraper and contact enricher for **WLW (Wer liefert was - wlw.de / wlw.at / wlw.ch)**, Europe's #1 B2B supplier, manufacturer, and industrial directory.

Automate targeted supplier research, extract complete corporate profiles, and automatically enrich listings with **direct company websites, verified business emails, and managing directors** from official homepages and Impressum pages.

***

### ⚡ The Game Changer: Why Choose This Scraper Over Generic Alternatives?

On standard directory scrapers, over **75% of company profiles do not display an email or phone number** because WLW restricts contact details behind paid supplier paywalls.

**Our Hybrid Advantage:**

- **✉️ Automated Multi-Source Email Enrichment:** If WLW doesn't provide a direct email, our engine automatically visits the company’s real website and `/impressum` to extract the **verified business email address**.
- **👔 Executive Decision-Maker Discovery:** Extracts the names of managing directors (*Geschäftsführer / Inhaber*) directly from official German imprint declarations.
- **📍 Structured Address Data:** Full company name, street address, postal code, city, and country (*Germany, Austria, Switzerland, etc.*).
- **🏭 Deep Industrial Demographics:** Workforce size ranges (e.g. `50-99 employees`), founding year, delivery scope (`Europe`, `Weltweit`), and supplier categories (`Hersteller/Fabrikant`, `Großhändler`, `Dienstleister`).
- **🚀 Ultra-Fast HTTP Stealth Engine:** No heavy headless browsers. Extracts up to 30 suppliers per page in milliseconds without expensive proxy overhead.

***

### 🎯 Typical Use Cases

- **Procurement & Sourcing Teams:** Discover qualified OEMs, specialized custom fabricators, and raw material suppliers across DACH.
- **B2B Outbound & Sales Operations:** Build targeted, decision-maker lead lists with verified corporate emails and phone numbers.
- **Market Mapping & Competitor Intelligence:** Map manufacturing capacities, certified suppliers, and workforce sizes in specific industrial niches.
- **Data Enrichment & CRM Sync:** Supplement existing corporate records with verified company homepages, addresses, and founding years.

// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish

## CLI example

```bash
echo '{}' |
apify call twc.api/wlw-b2b-supplier-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,twc.api/wlw-b2b-supplier-scraper"
        }
    }
}
```

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).
