Willhaben.at Scraper - Austrian Real Estate API

Extract real estate listings from willhaben.at, Austria's #1 classifieds portal for property. Returns rich structured data per listing: price, area, rooms, district, postcode, GPS, balcony details, agency, full image gallery, and publication time.

What you get per listing

• listingId, url, apiUrl — unique ID, direct link, and the willhaben public API URL
• listingType — sale or rent
• propertyType — willhaben's label (e.g. Wohnung, Dachgeschoßwohnung, Haus)
• title, description — listing headline + short teaser
• price (EUR, integer) and priceText — priceText keeps the published precision (e.g. "€ 1.063,39"), price is rounded to whole euros for clean filtering
• pricePerSqm
• rooms, areaSqm, floor
• balconyAreaSqm, balconyType — outdoor area in m² + type (Balkon, Terrasse, Garten, Loggia, …)
• state, district, postcode, location — Austrian Bundesland, Bezirk, PLZ, and full visible location text
• latitude, longitude
• agencyName, isPrivate — agency label, or isPrivate: true for private sellers
• publishedAt — ISO timestamp of publication
• imageUrl, imageUrls[] — cover image + full gallery
• scrapedAt

How to use

Easy mode (recommended): type an Austrian city, pick listing type and category.

{
  "city": "Vienna",
  "listingType": "sale",
  "propertyCategory": "apartment",
  "maxItems": 200
}

Other examples:

{ "city": "Graz",      "listingType": "rent", "propertyCategory": "apartment", "maxItems": 100 }
{ "city": "Salzburg",  "listingType": "sale", "propertyCategory": "apartment", "maxItems": 50  }
{ "city": "Innsbruck", "listingType": "rent", "propertyCategory": "house",     "maxItems": 100 }
{ "city": "Linz",      "listingType": "sale", "propertyCategory": "house",     "maxItems": 50  }

Built-in city slugs: Vienna/Wien, Graz, Linz, Salzburg, Innsbruck, Klagenfurt, Villach, Wels, Steyr, Dornbirn, Bregenz, Feldkirch, Sankt Pölten, Eisenstadt.

Power-user mode: for finer filters (price range, rooms, sub-area, project type, etc.), set them on willhaben.at, copy the URL from the browser, paste into searchUrl. The structured inputs are bypassed.

Common use cases

• Investor monitoring — track new listings across Vienna, Graz, Linz, Salzburg, Innsbruck; snapshot rent yields.
• Agencies / brokers — pull competitor inventory + agency activity for your market.

Data quality

In testing across Vienna, Graz, Linz, Salzburg, and Innsbruck (sample of 100+ listings, both sale and rent):

Field	Fill rate
price, priceText, areaSqm, rooms	~95-100% (rent "Preis auf Anfrage" listings legitimately have price: null)
location, district, postcode, state	100%
latitude, longitude	100%
publishedAt, agencyName, isPrivate	100%
propertyType	~95% (some commercial / Baugrundstück listings have null type)
imageUrl, imageUrls	~99%
balconyAreaSqm, balconyType	populated when the listing has an outdoor area; null otherwise

Pricing

Pay per result. See the Pricing tab. Failed runs cost nothing.

Notes

• The actor uses Apify's residential proxy (Austria) for reliable access. Transient errors trigger up to 2 automatic retries with a fresh proxy session.
• Pagination is automatic — set your desired maxItems and the actor walks through pages until it has enough or runs out.
• Rent listings on willhaben sometimes carry fractional prices (e.g. € 1.063,39) when the rent is calculated from a service-charge split. The actor rounds these to whole euros for price and preserves the original in priceText.
• If the actor returns 0 listings, it fails loudly with a diagnostic message rather than silently succeeding — common causes are a less-common city slug (try the power-user searchUrl mode) or anti-bot blocks.
