🛒 What is Kleinanzeigen.de Scraper (eBay Kleinanzeigen)?
Kleinanzeigen.de Scraper extracts eBay Kleinanzeigen ads from Kleinanzeigen.de (the classifieds site formerly called eBay Kleinanzeigen): title, price, description preview, all photos, exact publication time, GPS position and seller type, for any keyword, category, city, seller or search URL. Schedule it to monitor new ads.
Type a keyword (fahrrad), pick a category and a city, or paste any Kleinanzeigen search URL, click Start, and download the ads in JSON, CSV or Excel. No login, nothing to set up, and it is fast: about 1,000 ads in 40 seconds without details, about 100 ads with full details in a minute.
📋 What data can you extract from Kleinanzeigen.de?
One item per ad, 69 fields:
| Category | What you get |
|---|---|
| 🏷️ Ad | title, link, the site's ad number, offer or wanted ad, status, top ad, labels — AXA Solid Plus Fahrradschloss |
| 💰 Price | price and currency, fixed / negotiable (VB) / free, the price as the site shows it, buy now, offers accepted — 33 € |
| 📝 Text, photos and documents | description (preview; the full text with Extract details; plain text and the seller's own layout), every photo in full size, PDFs the seller attached |
| 🕒 Dates | publication time to the second, last edit — 2026-09-19 03:02:51 |
| 🗂️ Category and item details | category and parent category, every detail the seller filled in: make, mileage, size, rooms… — Art: Zubehör |
| 📍 Location | town (even where the site shows the district), district, postcode, federal state, street when given, GPS position — München, Hadern, 80689 |
| 👤 Seller | name (with Extract details), private or commercial, member since, rating and badges, link to all their ads — Autohaus Amelung |
| ☎️ Seller contacts (with Extract details) | phone number, e-mail and legal notice (imprint), when the seller published them — 02191479471 |
| 🏪 Shop | shop number, name and link of commercial sellers |
| 🚚 Shipping and payment | shipping possible, carriers, lowest shipping price, secure payment — 2.99 € |
| 👁️ Views | how many times the ad was viewed (option) |
| 🔎 Search | which search found the ad and at which position, when it was read, the site's untouched data (option) |
Every field, with an example, is listed in the Output section below.
Fields marked (detail) in the Output tab (description in full, sellerName, sellerPhone, sellerEmail, sellerImprint, street, shippingPriceFrom, offerPossible, securePaymentPossible, seller badges, lastEditedAt, documents) are filled only when Extract details is on (off by default: a listing-card-only scrape is much faster and cheaper). Tick it when you need the full description or the seller's contact.
🔎 eBay Kleinanzeigen scraper: every ad, one search or many
Kleinanzeigen.de is the German classifieds site formerly called eBay Kleinanzeigen. This scraper reads its ads the way the website shows them: pick a keyword, a category (Fahrräder & Zubehör), a city and a radius, or paste a search URL, a seller page or a single ad. Run it once, or schedule it with Only new ads to follow a search and get only the ads it has never returned.
✅ Why use Kleinanzeigen.de Scraper?
- 🚀 Fast: about 1,000 ads in 40 seconds in list mode, about 100 with full details in a minute (measured on Apify).
- 📚 Deep: up to 10,000 ads per search, eight times what the website itself pages through; a bigger search is split by category, city or price band (see Tips).
- ☎️ Seller contacts (with Extract details): the phone number the seller published with the ad (about 69 % of commercial sellers, 4 % of private ones), and the e-mail and legal notice of commercial sellers (an e-mail for about half of them), plus their name, rating, badges and registration date.
- 🎛️ Every filter of the site, including the per-category ones: car make and model, mileage, first registration, fuel, equipment, rooms, floor area… (
attributeFilters), plus price, radius, private/commercial, offers vs wanted ads, photo only, buy now. - 🗂️ Several searches in one run: keywords × cities, sellers and shops to follow, single ad ids — each with its own cap so that one big city cannot eat the whole budget.
- 🔔 Monitoring built in: tick Only new ads, schedule the Actor, and each run returns (and charges) only what it has never delivered before — the publication time is exact to the second, so an hourly run returns exactly the new ads.
- 📅 Date filters:
postedAfter: "24 hours"— with the default sort, a search stops at the first page that is entirely too old. - 🔌 API, scheduling, monitoring, integrations (Make, Zapier, n8n, Google Sheets…), proxy rotation and JSON/CSV/Excel export via the Apify platform.
🚀 How to scrape Kleinanzeigen.de
- Create a free Apify account.
- Open Kleinanzeigen.de Scraper and type a Search keyword (e.g.
fahrrad). - Narrow it down if you want: Category (
Fahrräder & Zubehör), Location (Berlin,10115) and Radius, price range, private or commercial sellers. - Or paste your own Kleinanzeigen URLs into Start URLs: any search results page (the filters and the sort written in the URL are kept, pagination is automatic), a seller page, or single ad pages.
- Set Max ads (100 by default, 0 = no limit) — and Max ads per search when you run several searches — then click Start and download the dataset in JSON, CSV, Excel or via API.
💰 How much does it cost to scrape Kleinanzeigen.de?
This Actor uses pay per event pricing: you pay for each ad, and for each option only when you turn it on — except that an ad you ask for by id or by URL is always read on its own page, so it is charged Details too.
| Event | Price per 1,000 |
|---|---|
| Ad (every row of the dataset) | $0.22 on Free, $0.21 on Bronze, $0.20 on Silver, $0.19 on Gold |
| + Details: the ad's own page (full description, seller name, phone, e-mail and imprint, badges, shipping price) — only when Extract details is ticked | + $0.14 on Free, $0.13 on Bronze, $0.12 on Silver, $0.11 on Gold |
+ View count (includeViewCount) | + $1.19 on Free, $1.18 on Bronze, $1.17 on Silver, $1.16 on Gold |
Filtered listing: an ad's own page read, then dropped by With phone number only (requirePhone) | $0.32 on Free, $0.31 on Bronze, $0.30 on Silver, $0.29 on Gold |
| Filter check: an ad dropped on its results page by a filter of this Actor (dates, excluded keywords, minimum photos, price types, shipping); an ad that passes the filters pays its row, not a check | $0.19 on Free, $0.18 on Bronze, $0.17 on Silver, $0.16 on Gold |
| Run start | $0.019 per run |
With the default settings (details off, list mode) 1,000 ads cost $0.22 on the Free plan; with Extract details on $0.36. Example on the Free plan: 20,000 ads with details ≈ $7.22; a daily monitor of 300 new ads with details ≈ $0.13 a day. An option is charged only on the ads that got it (a view counter that failed is not charged). Each ad dropped by one of the Actor's own filters (dates, excludeKeywords, minImages, priceTypes, shipping) is charged as a Filter check; an ad that passes them is charged as an ad, nothing more; with With phone number only (requirePhone) the phone is only on the ad's own page, so each page read and then dropped for lack of a phone is charged as a Filtered listing. With onlyNew, an ad dropped by the same filters in a previous run is remembered: it is neither read nor charged again. The filters sent to the site with the search (price, radius, seller type…) cost nothing extra. Platform usage (compute, proxy) is included in the price.

💡 Tips
How to get more results
One search returns at most 10,000 ads (the site's own limit). Beyond that, split it: by category, by city (locations), or by price band (minPrice / maxPrice) — every piece is a search of its own with its own cap. Set maxItems to 0 to take everything a search has.
How to reduce costs
The price is per ad, so the levers are maxItems, maxItemsPerQuery, the filters sent to the site with the search (price, radius, seller type, category filters: a listing they drop is never downloaded — the Actor's own filters are charged per ad they drop) and onlyNew for recurring runs (you never pay twice for the same ad). Leave extractDetails off (the default) when the card is enough (title, price, short description, photos, location, date, seller id and type): the ad then costs $0.22 per 1,000 instead of $0.36 (Free plan), and the run is much faster. Leave includeViewCount off unless you need the number of views.
Several searches in one run
Fill searchQueries and / or locations: the Actor runs one search per keyword × city (3 keywords × 4 cities = 12 searches, up to 500 per run). The single query and location fields still work and are added to the lists. Sellers (sellerIds) and shops (storeIds) are searches too: the category, the filters and the FIRST keyword and FIRST location of the input apply to them (one search per seller or shop, never one per keyword × city). An ad found by several searches is saved — and charged — once. Set maxItemsPerQuery to give every search its own cap.
Per-category filters (attributeFilters)
Every category of the site has its own attributes, and the Actor passes them all: run a first search, look at attributeList in the output (autos.marke, autos.km, haus_kaufen.zimmer…), and put what you need in attributeFilters. A name the site does not know filters nothing, so check attributeList rather than guessing.
Monitoring: only the new ads
Tick Only new ads (onlyNew) and schedule the Actor. The first run returns everything; each later run skips the ads already delivered: they are not saved, not charged, and their page is not even opened. The memory lives in a named key-value store of your account (kleinanzeigen-listings-scraper-seen, up to 150,000 ads per key) and is only updated with ads that really reached the dataset, so a failed run never hides anything. Give each schedule its own stateKey (two schedules sharing a key would hide each other's ads), and tick resetState once to start over. With the default sort (newest first), a search stops once it meets 500 ads in a row you already have — or, under a smaller maxItems / maxItemsPerQuery, once 80% of that cap are ads you already have (paid top ads pinned above the sort are not counted); another sort reads the search to its end or to your caps.
Filter by publication date
postedAfter and postedBefore take a date (2026-09-01, the whole day is included, German time zone) or a period before now (24 hours, 7 days, 2 weeks, 1 month; via the API also a full ISO date-time). The site gives the publication time to the second, so an hourly run with postedAfter: "1 hour" returns exactly the new ads. Each ad the date filter checks is charged as a Filter check, kept or not; filtered-out ads are not saved and do not count in maxItems; the run summary tells how many were filtered. With postedAfter and the default sort (newest first), a search stops at the first page that is entirely too old; another sort reads on, up to your caps, keeping only the recent ads.
🔌 Integrations and API
Call the Actor via the Apify API, the JavaScript or Python clients, or connect it with integrations and webhooks (Make, Zapier, n8n, Google Sheets, Slack, Airtable…). The dataset can be fetched as JSON or CSV from any tool.
🤖 Use with AI agents (MCP)
AI agents (Claude, ChatGPT, Cursor…) can find and run this Actor through the Apify MCP server, billed to their Apify account like any run. It returns one item per Kleinanzeigen.de ad. Actor id: nice_dev/kleinanzeigen-listings-scraper; MCP server with this Actor only: https://mcp.apify.com/?tools=fetch-actor-details,nice_dev/kleinanzeigen-listings-scraper.
Smallest input, for a cheap first call:
{"query": "fahrrad","maxItems": 10}
Key output fields: url, title, price, publishedAt, city, sellerName, sellerPhone, images.
Cost: $0.22 per 1,000 ads on the Free plan (details off, the default; $0.36 with Extract details on) plus $0.019 per run start; the view count and the filters cost extra, see the pricing section above. Cap each call with maxItems and, through the API, with the run option maxTotalChargeUsd.
❓ FAQ
Is it legal to scrape Kleinanzeigen.de?
The Actor only reads what Kleinanzeigen.de shows publicly to any anonymous visitor. It logs in to nothing. Results can contain personal data — a seller's name, and the phone number or imprint they chose to publish with their ad — which is protected by GDPR: do not store it without a legitimate reason, and do not use it for unsolicited marketing. You are responsible for using the data in compliance with Kleinanzeigen's Terms of Use and applicable law. This Actor is not affiliated with Kleinanzeigen.de or eBay.
Does it need a login or a proxy?
No login. The proxy is included in the price: leave the default setting (the residential proxy is not available). A request the site turns away is retried at once on a new proxy session, up to 10 times on top of the retries (without a proxy, after a pause of 5 seconds, doubled at each retry up to 150 seconds). Behind the Apify proxy, a request turned away on 3 proxy IPs (8 for the lookups made before the crawl) is then sent without proxy, and the run's log says so; with your own proxy URLs, every request goes through them.
Why am I charged for ads I did not get with requirePhone?
A phone number is only on the ad's own page, so With phone number only reads that page before it knows whether the seller published one. Each page read and then dropped is charged as a Filtered listing: the search is paid even when it finds few ads. Never charged as a Filtered listing: an ad dropped on its results page (another filter, a date — a Filter check there), an ad a previous run already delivered (onlyNew), a page that failed or an ad removed meanwhile, and never twice the same ad (a retry, a resurrected run). The run stops after 300 pages in a row without a phone — private sellers rarely publish one (about 4 %) — and never goes past your maximum cost: choose Seller type: Commercial sellers only to get far more phone numbers per page read.
Is the data safe to open in Excel or to show on a web page?
Titles and descriptions are the sellers' own words, copied as they are. A text can begin with -, +, = or @ (a phone number, a title such as -20% heute): Excel and Google Sheets may read such a cell of a CSV file as a formula or as a number. The Actor leaves the text as it is, so that the JSON and the API give the real value: when you open a CSV, import these columns as text. Every URL field holds an http(s) URL or null; descriptionHtml holds the seller's own markup, which the Actor does not sanitize. On a web page, escape every field like any text written by a stranger.
Known limitations
- One search returns at most 10,000 ads: split it (see Tips) to go further.
descriptionin full,sellerName,sellerPhone,sellerEmail,sellerImprint,street,offerPossible,securePaymentPossibleand the seller badges come from the ad's own page: they are empty (null,[], the short preview fordescription) whenextractDetailsis off.- A phone number is only there when the seller published one with the ad (about 69 % of commercial sellers, 4 % of private ones).
- A shop URL (
/pro/...) carries no id: use thestoreIda previous run returned. onlyNewremembers ad ids, not their content: an ad whose price changed is not returned again.- Two runs sharing the same
stateKeyat the same time may both return the same new ad. includeViewCountasks the site for the counter of each ad, which counts as one visit for the seller, exactly like opening the page in a browser.
A run that reaches its timeout stops itself about 45 seconds before it: no new page is asked, what it read is saved and, with onlyNew, remembered, and the run ends Succeeded with "Stopped before the run's timeout". In list-only mode with includeViewCount, the ads whose counter was not read yet are saved without it. Resurrect the run to go on from there, or give the next run a longer timeout (Run options).
A run the platform stops without warning (out of memory)
- Resurrect it: it goes on from where it stood at most a minute before the stop. What it had read since is read again, and the ads already saved are skipped: none is delivered or charged twice, and
maxItemsstill counts them. - With
onlyNew, the memory is saved after each write (at most once every 2 seconds): resurrect the stopped run and the ads it had saved meanwhile join the memory; leave it stopped for good, and the next run may return the ads of its last 2 seconds once more.
Something doesn't work?
The last line of the log counts the ads saved, filtered out and no longer on Kleinanzeigen.de (removed while the run was reading them), and the requests that failed after every retry. Those requests and the removed ads are listed, with the reason, in the FAILED_REQUESTS record of the run's key-value store. A run that saved nothing and had failed requests fails, and its last message gives the cause (a search URL that does not exist says so, instead of "run it again"). A run that saved some ads fails too when at least as many requests failed for good as were read (page 1 read, the next pages or the ad pages blocked), or — with includeViewCount — when at least as many view counters failed as were read (most rows would lack the view count you asked for): a green run with a short dataset would hide the outage. One failed request among many is only a warning.
If Kleinanzeigen.de changes its pages, you are told instead of paying for blank rows. A results page that counts ads but gives none the Actor can read, or an ad page that comes back empty, is an error (retried, then listed in FAILED_REQUESTS), never a quiet "No listings found". If the first 20 ads read all lack their title, publication date, seller id, seller type, postcode, place id, category, the amount of a price typed as an amount, the type of a price that has an amount or — with extractDetails — description, seller name or the imprint of a professional seller, the run saves nothing more, stops and fails, and its last message names the missing field: at most those first ads are charged. An ad that a filter drops because it lacks that field (postedAfter / postedBefore for the date, priceTypes for the price type) counts among those 20. A scheduled onlyNew run is judged on the first 20 ads of its pages, the ones a previous run already delivered included: if the site changed, it stops before saving anything. A run of fewer ads (a small Max ads) is checked at its end, from 5 ads: its ads are already saved, and the run fails with the missing field instead of ending green. If the site refuses the access of its app (HTTP 401), the run fails before reading anything and says so: running it again will not help, please report it.
