🛒 Marktplaats.nl Scraper

Want to find deals on Marktplaats or analyse the Dutch second-hand market? This scraper makes it super easy!

Use structured filters (keyword, category, price, postcode) — structured filters work better for AI agents — or paste an input_url straight from your browser once you've already filtered on Marktplaats. When input_url is set it overrides the filters below. Either way, you get listing data with prices, location, seller, and photos as CSV or JSON.

• 🤖 AI Agents: Power bots and OpenClaw workflows with real-time Marktplaats listings.

✨ Why you'll love this scraper

• 🔗 Input URL or Filters: Paste a Marktplaats results URL (input_url) if you already filtered in the browser — hash filters like #PriceCentsFrom:… are supported — or use structured filters (better for AI agents). input_url always wins when set; leave it empty when you want filters to apply.
• 🎯 Website-Matched Search: Uses Marktplaats’ own /lrp/api/search endpoint (same data as the site).
• 📍 Distance Search: Optional Dutch postcode + radius in km.
• 🗂️ Categories: All major L1 categories, plus optional L2 slug (e.g. bmw under Auto's).
• 🇳🇱 Built for the Netherlands: Nationwide Marktplaats inventory.
