Key features

• 🔔 Notifications — Telegram, Slack, Discord, WhatsApp Cloud API, and generic webhook out of the box. Pair with incremental for daily new-listing alerts without pipeline glue.
• ♻️ Incremental mode — recurring runs emit only directory entries that are new or updated — keep your supplier-outreach lists fresh without re-fetching the full directory. Saves 80–95% on weekly syncs.
• 🔗 Paste-mode — paste any wlw.de URL straight from your browser — single-listing pages, search-results URLs, or category SEO URLs. Mix freely with keyword and IDs in the same run; results dedupe by ID.
• 📧 Email + phone extraction — auto-extracted contact extractedEmails[] and extractedPhones[] on every directory entry — drop straight into your CRM or outreach tool.
• 🎯 Batch searches — pass ["term1", "term2"] for query, location, or city to batch multiple searches in one run — shared dedup state, single dataset, one Actor-Start charge instead of N.
• 📌 Change classification — each record carries a changeType of NEW / UPDATED / UNCHANGED / REAPPEARED / EXPIRED. Default emits NEW + UPDATED + REAPPEARED; opt into the others with emitUnchanged / emitExpired. Repost detection flags previously-expired listings that come back.
• 📤 Export anywhere — Download the dataset as JSON, CSV, or Excel from the Apify Console, or stream live via the Apify API and integrations (Make, Zapier, Google Sheets, n8n, …).

What data can you extract from wlw.de?

Each result includes Core listing fields (listingId, listingKey, uuid, slug, name, city, street, and zipcode, and more), detail fields when enrichment is enabled (description), contact information (phoneNumber and emailExisting), and company metadata (companyId). All fields are always present — unavailable data points are returned as null, never omitted.

Input

The main inputs are a search keyword and a result limit. Additional filters and options are available in the input schema.

Key parameters:

• query — Keyword to search for suppliers (e.g. "Pumpen", "Werkzeugmaschinen"). Use JSON array for multiple queries.
• startUrls — Direct wlw.de search URLs to scrape.
• maxResults — Maximum number of companies to return (0 = unlimited). (default: 0)
• maxPages — Maximum search result pages to scrape per query (0 = unlimited, ~30 companies/page). Defensive safety bound — maxResults is the primary record cap. (default: 0)
• supplierType — Filter results to a specific supplier type. Valid values: production, distribution, service, wholesaler, customer_specific_manufacturing.
• countries — Post-extraction country filter. Only return companies whose countryCode matches one of the specified ISO 3166-1 alpha-2 codes (e.g. ["DE", "AT", "CH"]). Applied after scraping — all pages are fetched regardless.
• incrementalMode — Track new, updated, and removed companies across runs. Requires stateKey. (default: false)
• stateKey — Optional stable identifier for the tracked search universe. Leave empty to auto-derive a stable identifier from your search inputs — different keyword/location/filter combinations get isolated state automatically.
• emitUnchanged — When incremental, also emit companies that haven't changed. (default: false)
• emitExpired — When incremental, also emit companies no longer found in search results. (default: false)
• telegramToken — Telegram bot token from @BotFather. Required for Telegram notifications.
• telegramChatId — Telegram chat or channel ID where alerts are sent (e.g. "-100123456789" for a private group, or "@yourchannel").
• ...and 11 more parameters

Input examples

Basic search — Keyword-driven search with a result cap.

→ Full payload per result — all standard fields populated where the source provides them.

{
  "query": "Pumpen",
  "maxResults": 50
}

Incremental tracking — Only emit companies that changed since the previous run with this stateKey.

→ First run builds the baseline state. Subsequent runs emit only records that are new or whose tracked content changed. Set emitUnchanged: true to include unchanged records as well.

{
  "query": "Pumpen",
  "maxResults": 200,
  "incrementalMode": true,
  "stateKey": "pumpen-tracker"
}

Output

Each run produces a dataset of structured listing records. Results can be downloaded as JSON, CSV, or Excel from the Dataset tab in Apify Console.

Incremental fields

When incremental: true, each record also carries:

• changeType — one of NEW, UPDATED, UNCHANGED, REAPPEARED, EXPIRED. Default output covers NEW / UPDATED / REAPPEARED; set emitUnchanged: true or emitExpired: true to opt into the others.
• firstSeenAt, lastSeenAt — ISO-8601 timestamps tracking the listing across runs.

How to scrape wlw.de

1. Go to WLW Scraper in Apify Console.
2. Enter a search keyword.
3. Set maxResults to control how many results you need.
4. Click Start and wait for the run to finish.
5. Export the dataset as JSON, CSV, or Excel.

Use cases

• Extract listing data from wlw.de for market research and competitive analysis.
• Monitor new and changed listings on scheduled runs without processing the full dataset every time.
• Use structured location data for regional analysis, mapping, and geo-targeting.
• Export clean, structured data to dashboards, spreadsheets, or data warehouses.

How much does it cost to scrape wlw.de?

WLW Scraper uses pay-per-event pricing. You pay a small fee when the run starts and then for each result that is actually produced.

• Run start: $0.005 per run
• Per result: $0.0015 per listing record

Example costs:

• 10 results: $0.02
• 100 results: $0.15
• 500 results: $0.76

Example: recurring monitoring savings

These examples compare full re-scrapes with incremental runs at different churn rates. Churn is the share of listings that are new or whose tracked content changed since the previous run. Actual churn depends on your query breadth, source activity, and polling frequency — the scenarios below are examples, not predictions.

Example setup: 250 results per run, daily polling (30 runs/month). Event-pricing examples scale linearly with result count.

Churn rate	Full re-scrape run cost	Incremental run cost	Savings vs full re-scrape	Monthly cost after baseline
5% — stable niche query	$0.38	$0.02	$0.36 (94%)	$0.71
15% — moderate broad query	$0.38	$0.06	$0.32 (84%)	$1.84
30% — high-volume aggregator	$0.38	$0.12	$0.26 (69%)	$3.53

Full re-scrape monthly cost at daily polling: $11.40. First month with incremental costs $1.07 / $2.16 / $3.79 for the 5% / 15% / 30% scenarios because the first run builds baseline state at full cost before incremental savings apply.

Platform usage (compute and proxies) is billed separately by Apify based on actual consumption. Incremental runs consume less on result processing, though fixed per-run overhead stays the same.
