Marktplaats Scraper — Dutch & Belgian Classifieds Data (NL + BE)

Scrape marktplaats.nl and its sister platforms 2dehands.be and 2ememain.be — one shared backend, one dataset — by keyword or by pasted URL. Get listing title, price and price type, full description, city and coordinates, category, attributes, image URLs, view and favorite counts, plus seller lead-generation data: seller name and ID, verified/professional status, profile and all-ads URLs, reviews URL, own-website link, member-since date, contact options and city. One row per listing, tagged with its platform.

Built for Dutch and Belgian classifieds market research, competitor price monitoring, seller lead generation, and building structured resale databases. The default dataset is one row per listing, optionally enriched from the listing's own detail page.

Scrape Dutch & Belgian Classifieds For Market Research & Lead Generation

• Price monitoring on marktplaats.nl — fixed, bid, free or negotiable price types with view and favorite counts
• Seller lead generation — seller name, ID, verified/professional status, profile and all-ads URLs, reviews URL and contact options
• Cross-border market coverage — one platform: "all" run fans the same keyword out to the Netherlands and both Belgian platforms
• Building a resale or e-commerce database — full description, attributes map, image URLs and category tree
• Competitor and inventory research — category browsing with parent category and postedAt timestamps
• Vehicle and product attribute extraction — attributes / attributesRaw carry brand, mileage, fuel type and similar structured fields where the listing publishes them

How It Works

The Actor reads the internal search JSON behind Marktplaats, 2dehands and 2ememain, then follows offset pagination without a browser. Detail pages add the full description, exact posting date and seller lead fields.

Each row covers one listing with its price type, category, location, images, seller profile and contact options. Use it to track prices and build seller lead lists across the Benelux.

No browser is used — this is a plain HTTP CheerioCrawler. Three public surfaces are read, in order of preference:

1. Internal search/browse JSON API (primary). GET https://www.marktplaats.nl/lrp/api/search?query=<q>&limit=50&offset=0&searchInTitleAndDescription=true&viewOptions=list-view (same path on 2dehands.be and 2ememain.be) returns the same payload the page renders: listings[], totalResultCount, facets, searchRequest, categoriesById. It needs no cookies, no consent cookie, no auth and no JavaScript, and it makes pagination trivial (offset / limit, up to 50 per page).
2. Embedded __NEXT_DATA__ JSON blob. For a user-supplied search or category URL, the served Next.js HTML embeds the whole first result set and the exact original search request (props.pageProps.searchRequestAndResponse), which is then replayed against the JSON API for pages 2..n.
3. Inline state blobs on the listing (VIP) page. window.__CONFIG__ carries the price, the exact posted timestamp (stats.since), the full category, the seller object (ID, name, type, active-since, profile and all-ads URLs, contact options), the gallery image URLs and the ad type; window.__ENV_CONFIG__ carries the seller's reviews URL and the /externalUrl/redirect/… link to the seller's own website; and the DOM holds the full, untruncated description. These are fetched with plain HTTP through the crawler's request function, so the enrichment adds no rendering cost.

All three hosts return HTTP 200 to a normal request, so PlaywrightCrawler is never needed — that keeps runs fast and cheap.

Automate Classifieds Monitoring With Schedules & Webhooks

• Schedule the Actor daily or weekly to re-run a keyword and diff new listings, price drops and new sellers.
• Webhooks — configure a run-success webhook so each finished run POSTs to n8n, Make or Zapier and lands in a CRM or spreadsheet.
• Dataset views — pin the "Seller leads" view when the goal is outreach rather than market analysis.
• Apify API — pull the dataset programmatically with the JavaScript or Python client, or export JSON / CSV / Excel from the console.
• Recurring runs are what keep a resale database current; listings and prices move daily.

Frequently Asked Questions

Why use this Actor instead of the official Marktplaats API?

Marktplaats does operate an official API (API 2.0), but it is seller-side only: through it you have access to your own ads, and ads from other advertisers are not accessible. There is also a deep-pagination cap on that API (5,000 results). This Actor instead reads the same first-party search endpoint the site's own frontend calls, so you can search and export anyone's listings — including full descriptions, exact posted timestamps and seller lead fields — with no API key and no contract.

What are alternatives to Marktplaats for Dutch and Belgian classifieds data?

Three routes exist. First, the official Marktplaats API — free, but only for your own advertisements and capped at 5,000 results. Second, third-party classifieds APIs that resell Marktplaats data (and 2dehands / 2ememain) at a higher per-record price. Third, self-serve scraping of the same public JSON endpoint (this Actor and the ones in Related Actors). OLX is the usual companion for markets outside the Netherlands and Belgium.

Can I search 2dehands.be and 2ememain.be too?

Yes — set platform: "all". All three sites are served by the same codebase and the same /lrp/api/search endpoint, so only the hostname changes; rows are tagged with platform and de-duplicated on platform + itemId. You can also set platform to 2dehands or 2ememain to target one Belgian site.

Does this Actor return the full description and the exact posted date?

Yes, but only when includeDetails is true (the default). The search endpoint returns a description truncated to roughly 200 characters and a human-readable postedLabel; the listing page's inline state objects supply the full untruncated text and an exact ISO 8601 postedAt from stats.since. With details off you still get the truncated description and the label.

How much data can I get out of one search?

The backend caps each result page at 50 listings and allows roughly 100 pages per query, so a single query tops out near 5,000 listings. maxPagesPerSearch (default 3) and maxItems (default 100) are the Actor's own limits on top of that. Free-plan runs are capped at 10 items and 1 result page per search.

Can an AI agent call this Actor?

Yes. It is a standard Apify Actor, so any MCP client or agent can start a run through the Apify API or the Apify MCP server, wait for it to finish, and read the dataset items. The minimal input and output field list are in the next section.

How much does it cost?

Pay-per-event: one result event per listing returned ($1 per 1,000 listings), plus a small Actor-start event scaled by memory. There is no charge for backend pages that return no listing.

For AI Agents & LLM Apps

Purpose: return structured classifieds listings (title, price, description, location, category, attributes, images, seller lead fields) from marktplaats.nl, 2dehands.be and 2ememain.be as JSON rows.

Minimal input (the default — a single keyword on marktplaats):

{ "searches": ["fiets"] }

Variant — three keywords fanned out across all three platforms, with a higher cap:

{
  "searches": ["racefiets", "veldrijfiets", "stadsfiets"],
  "platform": "all",
  "maxItems": 300,
  "maxPagesPerSearch": 6
}

Output fields (default dataset): platform, itemId, url, title, priceEur, priceType, priceTypeLabel, isAuction, isFree, description, descriptionTruncated, city, country, latitude, longitude, distanceMeters, categoryId, category, categoryParent, attributes, attributesRaw, images, imageCount, primaryImage, sellerId, sellerName, sellerVerified, sellerType, sellerIsProfessional, sellerProfileUrl, sellerAdsUrl, sellerReviewsUrl, sellerWebsiteUrl, sellerActiveSince, sellerContactOptions, sellerCity, sellerCountry, postedLabel, postedAt, priorityProduct, traits, verticals, viewCount, favoriteCount, adType, reserved.

Behaviors an agent should know:

• searches and startUrls are the two drivers. searches runs one backend query per keyword; startUrls accepts search pages, category pages or single listing URLs. If both are given, both are processed.
• platform controls the host: marktplaats (default), 2dehands, 2ememain, or all to fan one keyword out to all three (rows are tagged platform and de-duplicated on platform + itemId).
• includeDetails defaults to true and is what supplies the full description, the exact postedAt and the seller lead fields; setting it to false leaves you with the search endpoint's ~200-character description and a postedLabel only.
• maxPagesPerSearch (default 3) caps backend pages per keyword at 50 listings each; the backend itself allows roughly 100 pages per query before it runs dry.
• sellerWebsiteUrl is a /externalUrl/redirect/… path (a working lead link), not a bare domain, and only exists when the seller published a website.
• postedAt is only populated when includeDetails is true.
• Free-plan runs are capped at 10 items and 1 result page per search.

Billing: pay-per-event — one result event per listing returned ($1 / 1,000). Budget by listing count, not by page count, since backend pages that yield no listing bill nothing.
