Immowelt Real Estate API
Live Immowelt data, fetched the moment you ask and handed back in a clean, structured form. Use it in your own app, a spreadsheet or as a tool for an AI assistant.
What you can get: Property search & exposé details for rent and sale (immowelt.de, Immonet).
Limited availability right now. Immowelt blocks requests from our data-center servers; it needs a residential proxy. Until then most requests end with a 502 “blocked” error, which costs no quota. Current success rates are on the status page.

What teams build with Immowelt data
Apartments, houses, plots and commercial properties for rent and sale from immowelt.de, one of Germany's largest property portals (Immonet listings included). Search by city, district or zip with radius, price, rooms, living space and sorting, or fetch a full exposé: cold/warm rent, additional costs, deposit, purchase price, price per m², living space, plot area, rooms, floor, year built, energy class and consumption, heating, features, images and floor plans. Field names shared with the other real-estate APIs. Privacy by design: only the seller type and agency company names – no names, phone numbers, e-mail addresses or street addresses; descriptions are redacted, coordinates rounded to about 1 km.
- Rent & price-per-m² analysis
- Investment screening
- Market reports by city and district
- Listing alerts
Works with AI assistants
Models only know what they saw in training. Add the Immowelt endpoints as a tool in ChatGPT, Claude, Gemini or your agent framework, and your assistant can look up current data while it answers.
Immowelt endpoints
All Immowelt endpoints are served under the /imw prefix and share the same API key and quota as every other platform.
