Marktplaats Search Scraper

Search Marktplaats.nl listings programmatically and get clean, structured JSON — with price & distance filters, multi-query fan-out, and optional deal analysis that flags underpriced items.

What it does

• 🔎 Search any term(s) — iphone 13, festool ts55, racefiets… multiple queries are merged and deduplicated.
• 💶 Price filters — set a min and/or max price in EUR.
• 📍 Location filters — search around a Dutch postcode within an adjustable radius.
• ↕️ Sorting — relevance, price (low→high / high→low), distance, or newest.
• 🔥 Deal analysis (optional) — computes a fair-value median across results and tags each listing as fire (≤72% of median), cheap (≤90%) or normal, plus a trap flag for likely defective/locked items.
• 🛡️ Robust at scale — proxy rotation, user-agent rotation, retries with exponential backoff, and polite rate limiting.
