}About the wlw.de API
The wlw.de API provides access to B2B supplier and product data from Germany's Wer liefert was marketplace across 4 endpoints. Use search_companies to find suppliers by keyword, industry type, employee count, or country, and get_company_details to retrieve full profiles including VAT ID, founding year, certificates, and named contacts with phone numbers.
Search and Filter B2B Suppliers
The search_companies endpoint accepts a query string (e.g. kunststoff, metall) alongside optional filters: countries (DE, AT, CH), supplier_types (production, service, distribution), employee_counts (e.g. 10-19, 100-199), and a verified boolean. Results are paginated via the page parameter and each company object in the response includes id, name, slug, city, description, phone_number, supplier_types, and employee_count. The total field tells you how many matching companies exist across all pages.
Full Company Profiles
get_company_details takes a slug obtained from search_companies results and returns a structured profile: name, vatId, address (with addressLines, city, postalCode, countryCode), contacts (array with firstName, lastName, phoneNumber, executiveType), certificates, foundingYear, employeeCount, and supplierTypes. This endpoint is the primary path to verified contact details and compliance-relevant data like certifications and VAT numbers.
Product Search and Featured Listings
search_products searches product and service listings by keyword, returning a products array where each item carries name, slug, description, associated company info, images, and pricing fields. The totalCount field shows full result volume across pages. For homepage-level discovery, get_homepage_featured requires no inputs and returns an array of currently trending product objects with slugId, productName, productPic, linkUrl, minPrice, and maxPrice — useful for monitoring which categories are actively promoted on the platform.
- Build a supplier discovery tool for procurement teams sourcing German industrial manufacturers by keyword and employee size.

- Monitor which products and price ranges are featured on wlw.de's homepage using get_homepage_featured.

- Aggregate product listings with minPrice and maxPrice fields from search_products for competitive pricing research.
- Track supplier distribution across DE, AT, and CH using the countries filter in search_companies.
- Identify service providers versus manufacturers in a niche by filtering supplier_types in search_companies.
