Immowelt Germany Real Estate Scraper

---

🎯 What this scrapes

Immowelt.de is Germany's #2 property portal, and its rival cluster is deep: 30 Actors already target it on the Apify Store, 17 with real users, the leader running 714 jobs a month. (Germany's #1 portal, ImmoScout24, is deliberately out of scope here — two incumbents there each out-run our entire top earner combined, an impossible field to enter.) This Actor pulls every listing card off an Immowelt search page — Berlin, Munich, Hamburg, or any city/district you search — and normalizes it into clean numeric fields: a bare EUR price, living area in m², room count, and district, instead of the single German blob string ("Wohnung zum Kauf - Treptow-Köpenick - 170.000 € - 2 Zimmer, 45 m²") the site actually renders. Both kaufen (sale) and mieten (rent) listings work the same way.

🔥 What we handle for you

• 🛡️ Browser fingerprint rotation — curl-cffi impersonates real Chrome / Firefox / Safari TLS handshakes, rotated across requests, so the target sees a browser, not Python.
• 🌐 Proxy session rotation via Apify Proxy — fresh session and exit IP on every block, always pinned to a German (DE) exit so you never get a wrong-country page silently.
• 🔁 Retries with exponential backoff on 408 / 429 / 5xx — up to 5 attempts per search URL, Retry-After honoured.
• 🧱 Search-URL- and listing-level fault isolation — one blocked search URL or one bad card is skipped and logged, never crashes the run.
• 🧊 Clean, typed dataset rows — Pydantic-validated, ISO-8601 timestamps, numeric price/area fields with an explicit currency and unit instead of one unparsed German string.
• 💰 Pay-Per-Event pricing — you only pay for results that hit your dataset. No data, no charge.

💡 Use cases

• Home-buyer market research — pull current kaufen listings for a German city, normalized price-per-m² included, to compare districts fast.
• Rental market benchmarking — track mieten listing prices and living area across Berlin, Munich, and other cities.
• PropTech and real-estate analytics — feed a clean, deduped listings dataset into a pricing or valuation model.
• Relocation services — build client-facing property shortlists with district and room-count data included.

⚙️ How to use it

1. Click Try for free at the top of the page.
2. Paste one or more real immowelt.de search URLs (copy them straight from your browser — a bare city name alone won't resolve, Immowelt encodes a location-ID hash in every search URL).
3. Click Start. Output streams into the run's dataset.
4. Export from Storage → Dataset as JSON, CSV, or Excel — or fetch via the API.

🚧 Limitations

v1 is search-results only — no detail-page enrichment. Immowelt's /expose/<uuid> detail pages sit behind a DataDome challenge that curl-cffi cannot clear, so fields only the detail page carries (bathrooms, year built, energy label, HOA fee, plot area, full address) are out of scope for v1. Numbered pagination is a client-side control that doesn't respond to a URL page parameter, so breadth comes from supplying more search URLs (different cities/districts), not from a page cursor. district is null when a card's title doesn't carry one (e.g. some commercial/land listings).

❓ FAQ

Do I need an Immowelt account or API key?

No. This Actor scrapes Immowelt.de's own publicly listed property data — no login, no API key.

Why can't I just pass a city name?

Immowelt encodes an opaque location-ID hash in every real search URL (.../berlin-10115/ad08de8634). A bare city path 410s. Search on immowelt.de, apply your filters, then paste the resulting URL in.

Why is there no enrich option like some of your other real-estate Actors?

Immowelt's detail pages are protected in a way this Actor's HTTP-level approach can't clear. Rather than ship a broken toggle, v1 sticks to the search-card data, which already carries price, area, rooms, and district.

Can I scrape multiple cities in one run?

Yes — pass multiple search URLs and we fetch and dedupe across all of them.
