Immowelt.de API scraper - German real estate data: apartments and houses for sale

base /immowelt/v13 endpoints

post/immowelt/v1/search1 credit

Search Immowelt.de property listings in any German city, district, postcode area or federal state - for sale, to rent or foreclosure auction - with structured filters: price (EUR), number of rooms, living space (m2), plot size (m2), property type and subtype (penthouse, loft, detached house, villa...), new-build only, and features such as garden, cellar or lift. Results are 30 per page and can be sorted by price, date or size. Each row carries the numeric price, rooms, living space, plot, address (city/district/postcode), energy class, publication date, photos and the listing agency. `location` takes plain German free text ('Berlin', 'Muenchen', 'Koeln') and is resolved to Immowelt's own geo-id, or you can pass a geo-id ('AD08DE8634') straight through.

post/immowelt/v1/detail1 credit

Full record for one Immowelt listing, by its expose URL or its listing id. Returns the asking price or monthly rent with running costs and commission, rooms, living space, plot, year built, condition, heating and energy source, the complete feature and energy-certificate table, the full German description and neighbourhood text, every photo at full resolution, the market price-per-m2 comparison Immowelt itself publishes for the area, and the listing agency. Both Immowelt id spaces are accepted - the short online id from a search row ('256Q14GY2JL7') and the legacy UUID in an older expose link - and both are returned so a row can be joined either way.

Parameter		Allowed / range	Description
listing	required	—	An Immowelt expose URL (https://www.immowelt.de/expose/<id>) or just the id. Both the short online id ('256Q14GY2JL7', what a search row's `id` gives you) and the legacy UUID ('1215b46c-9e03-4081-bc72-67209544ff9f') work.
