The recorded `search` ( `per_page=20`, `zip_codes[]=2100`, `listing_type=sale`, `sort_by=price`, `price_max=8000000`) returns `results`, each with `id`, `listing_type`, `status`, `url`, `address`, `address_type`, `price`, `monthly_expense`, `price_per_area`, `area`, `rooms`, `year_built`, `energy_label`, `days_on_market`, `open_house`, `financing` and `realtor`. Each `address` carries `address_id`, `latest_valuation` and `sales_history`. It also returns `total_hits` (173), `total_pages` and `has_more`. ## How a call works Search homes for sale in København Ø: `GET /v1/boligsiden/search?per_page=20&zip_codes[]=2100&listing_type=sale&sort_by=price&price_max=8000000` with your key in the `X-API-Key` header. Each result's `id` goes to `listing`, its `address.address_id` to `address`, and its `realtor.id` to `agency`. Every successful call costs 1 credit; failed calls cost nothing.

New accounts get free credits to start, and credit packs bring the price down as you scale. **What format are responses in?** Every endpoint returns JSON, with no HTML parsing on your side. **Can I get sold prices for an address?** Yes. Each search result's \`address\` includes \`sales\_history\`, and you can pass its \`address\_id\` to \`address\` as \`id\`. **Should I build a Boligsiden scraper instead?** You can, but a Boligsiden scraper is code you maintain: page changes break it, requests get blocked, and Boligsiden's terms govern how you collect data. The Boligsiden API gives you 10 endpoints of named JSON fields for 1 credit per successful call, and failed calls cost nothing. A scraper makes sense only for data these endpoints don't return, so check the response in the playground on this page first. ## Try the Boligsiden API with 100 free credits No credit card.
