Output

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

{

  "companyId": "100001",

  "description": "Example industrial supplier description for documentation only.",

      "email": "max.mustermann@mustertechnik.example",
      "phoneNumber": "+493012345679",

    }
  ],
  "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
