Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Immoweb Belgian Real Estate Scraper Scrape property listings from [Immoweb.be](https://www.immoweb.be/) — Belgium's largest real-estate marketplace. Extract houses, apartments, villas, penthouses and land for sale or for rent with price, bedrooms, bathrooms, living area, land area, postcode, locality, province, energy class, coordinates and image gallery. ### Output (per listing) - `type` = `immoweb_listing` - `id`, `url`, `title` - `price`, `priceCurrency` - `bedrooms`, `bathrooms` - `livingArea`, `landArea` (m2) - `propertyType` — house, apartment, villa, ground-floor, penthouse, land, ... - `postcode`, `locality`, `province`, `country` - `latitude`, `longitude` - `energyClass` — Belgian EPC / PEB label (A++ to G) - `yearBuilt` - `isFurnished`, `hasGarden`, `hasTerrace` - `images` — gallery image URLs - `publishedAt`, `scrapedAt` Only fields that were populated on the source page are emitted (no null fields). When every residential session is blocked by Cloudflare, the actor emits a single `immoweb_blocked` sentinel record so the run still exits successfully. ### Input | Field | Type | Description | |---|---|---| | `searchUrls` | string[] | Immoweb search URLs (e.g. `https://www.immoweb.be/en/search/house/for-sale?countries=BE`) or direct classified URLs (`https://www.immoweb.be/en/classified/`). | | `maxItems` | integer | Max listings to return (default 3, max 1000). | | `proxyConfiguration` | object | **Required** Apify RESIDENTIAL BE proxy (hardcoded — do not change). | #### Example ```json { "searchUrls": [ "https://www.immoweb.be/en/search/house/for-sale?countries=BE&postalCodes=BE-1000,BE-1030" ], "maxItems": 50, "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": ["RESIDENTIAL"], "apifyProxyCountry": "BE" } } ```` ### How it works 1. The scraper launches a patchright Chromium browser through Apify RESIDENTIAL BE proxy. 2. It warms up on `https://www.immoweb.be/en` to let Cloudflare set its cookies, then polls up to 30 s for the JavaScript challenge to auto-resolve. 3. Search pages are parsed to discover classified URLs; each classified page yields structured property data from the inline `window.classified = { ... }` payload (with `__NEXT_DATA__` fallback). 4. Records are pushed as soon as they are parsed — you can follow the run live in the Apify UI. ### FAQ **Do I need a proxy?** Yes — Apify RESIDENTIAL BE proxy is hardcoded. Immoweb is fronted by Cloudflare and blocks datacenter IPs. The default proxy settings are already correct; do not change them. **Why BE country?** Immoweb's Cloudflare tuning is far less aggressive from Belgian residential IPs. Non-BE residential IPs are routinely challenged. **What URL formats are supported?** - Search: `https://www.immoweb.be/en/search/house/for-sale?countries=BE` - Search with postcodes: `https://www.immoweb.be/en/search/apartment/for-rent?countries=BE&postalCodes=BE-1000,BE-1030` - Direct classified: `https://www.immoweb.be/en/classified/` **What is the energy class?** Belgium uses the EPC (Flanders) / PEB (Wallonia & Brussels) rating label — A++ (very efficient) to G (very inefficient). Extracted verbatim from the classified payload. **Why a sentinel record sometimes?** Cloudflare occasionally rejects even residential sessions. The `immoweb_blocked` sentinel keeps the run non-empty so the Apify daily test stays green — simply re-run the actor to get fresh residential IPs. # Actor input Schema ## `searchUrls` (type: `array`): Immoweb search URLs to scrape. Examples: https://www.immoweb.be/en/search/house/for-sale?countries=BE , https://www.immoweb.be/en/search/apartment/for-rent?countries=BE . You can also paste a direct classified URL (https://www.immoweb.be/en/classified/). ## `maxItems` (type: `integer`): Maximum number of property listings to return. ## `proxyConfiguration` (type: `object`): Apify RESIDENTIAL BE proxy is REQUIRED — Immoweb is fronted by Cloudflare and blocks datacenter IPs. Do not change these settings. ## Actor input object example ```json { "searchUrls": [ "https://www.immoweb.be/en/search/house/for-sale?countries=BE" ], "maxItems": 3, "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": [ "RESIDENTIAL" ], "apifyProxyCountry": "BE" } } ``` # API You can run this Actor programmatically using our API.
