❓ Frequently Asked Questions

Q: How many listings can I extract? A: FREE tier: 25 per run. PAID tier: unlimited.

Q: What's the difference between Overview and Detail? A: Overview returns the search-card fields (price, rooms, area, address, energy, agent) fast and cheap. Detail visits each listing for the full set — price breakdown, GPS, build year, features, private/agent.

Q: Do I need an Immowelt account or API key? A: No. Just paste a search URL or pick a region.

Q: What output formats are available? A: JSON, CSV, Excel — export directly from the Apify dataset.

Q: Can I scrape a whole city or all of Germany? A: Yes. Note Immowelt's pager caps a single query at ~10,000 results — split large regions by price/type bands to enumerate fully.

Q: Are prices available in USD? A: Yes — every row carries price_usd at the run's live FX rate, plus price_per_sqm.

Q: Is this legal? A: We only extract publicly available data. See the legal note below.

🐛 Troubleshooting

No results returned

• Confirm the search URL opens real listings in a browser
• Widen filters (price/rooms/area) — they may be too narrow
• For byQuery, verify the geoId token (use bySearchUrl if unsure)

Fewer results than expected

• Immowelt caps a single query at ~10,000 listings; split by region/price bands
• Check maxResults and maxPages

Missing detail-only fields (GPS, deposit, build year)

• Those appear in Detail mode only — switch scrapeMode to detail

⚖️ Is it legal to scrape data?

Our actors are ethical and do not extract any private user data, such as email addresses, gender, or location. They only extract what the user has chosen to share publicly. We therefore believe that our actors, when used for ethical purposes by Apify users, are safe.

However, you should be aware that your results could contain personal data. Personal data is protected by the GDPR in the European Union and by other regulations around the world. You should not scrape personal data unless you have a legitimate reason to do so. If you're unsure whether your reason is legitimate, consult your lawyers.

You can also read Apify's blog post on the legality of web scraping.
