## What's an Apify Actor?

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.

# README

## Kamernet Scraper — Dutch Rooms, Apartments & Studios

Extract rental listings from **[Kamernet.nl](https://kamernet.nl)**, the largest room-rental platform in the Netherlands, as clean structured JSON. Search any city, filter by rent, size and property type, and get every field that matters: price, surface area, availability dates, deposit, exact address with GPS coordinates, house rules and photos.

Built for the Dutch housing market's #1 problem: **speed**. Rooms in Amsterdam or Utrecht are gone within hours — the built-in **monitoring mode** outputs only listings that are new since your last run, so you can pipe fresh listings straight into alerts, a Slack channel or your own app within minutes of them going live.

### What you get

Each listing is one JSON object:

```json
{
  "listingId": 2380154,
  "url": "https://kamernet.nl/en/for-rent/room-amsterdam/gerard-schaepstraat/room-2380154",
  "listingType": "room",
  "city": "Amsterdam",
  "street": "Gerard Schaepstraat",
  "postalCode": "1052GK",
  "latitude": 52.379791,
  "longitude": 4.875219,
  "totalRentalPrice": 1503,
  "currency": "EUR",
  "utilitiesIncluded": false,
  "deposit": 2750,
  "agencyFee": 250,
  "surfaceArea": 84,
  "furnishing": "unfurnished",
  "availabilityStartDate": "2026-07-01T00:00:00",
  "availabilityEndDate": null,
  "title": "In search of a roommate",
  "description": "LOOKING FOR ROOMMATE / ROOM AVAILABLE in shared flat…",
  "candidatePetsAllowed": false,
  "candidateSmokingAllowed": false,
  "isNewAdvert": true,
  "imageUrls": ["https://resources.kamernet.nl/image/…"],
  "scrapedAt": "2026-07-02T21:40:00.000Z"
}
````

Turn off **Fetch full details** for a faster, cheaper run with the core fields only (price, size, type, street, availability, photo).

### Use cases

- **Rental alerts** — run on a 15–30 min schedule with *New listings only* enabled; connect a webhook, Zapier/Make, or email integration and beat the crowd to every new room.
- **Market research** — rent per m² by city or neighbourhood, supply trends, furnishing and deposit statistics across the NL housing shortage.
- **Relocation & expat services** — feed live inventory for clients moving to the Netherlands.
- **Aggregators & portals** — keep your Dutch rental coverage complete and current.

### Input

| Field | Type | Notes |
|---|---|---|
| `cities` | array | One or more Dutch cities, e.g. `["Amsterdam", "Utrecht", "Den Haag"]` |
| `listingTypes` | array | Any of `room`, `apartment`, `studio`; empty = all |
| `maxRentEur` | integer | Max monthly rent in € (Kamernet filters in €100 steps) |
| `minSizeM2` | integer | Minimum surface in m² |
| `radiusKm` | integer | 1, 2, 5, 10 or 20 km around the city |
| `sort` | string | `newest` (default), `cheapest`, `most_expensive` |
| `maxListings` | integer | Cap per run (default 200) — keeps costs predictable |
| `fetchDetails` | boolean | Full record incl. description, address, deposit, coordinates (default `true`) |
| `newListingsOnly` | boolean | Monitoring mode: only listings not seen in previous runs of the same search |
| `language` | string | `en` (default) or `nl` for title/description |

Minimal example:

```json
{
  "cities": ["Utrecht"],
  "maxRentEur": 900,
  "newListingsOnly": true
}
```

### Monitoring mode — how it works

With `newListingsOnly` enabled, the actor remembers which listing IDs it has already output **per search configuration** (same cities + filters = same memory). Each run outputs only genuinely new listings — no client-side deduplication needed. Change the filters and you get a fresh memory automatically.

Typical setup: schedule the actor every 15–30 minutes, add the platform's **webhook or email integration** on new dataset items, and you have a real-time Kamernet alert service for exactly the search you care about.

### Export & integrations

Results land in an Apify dataset — export as **JSON, CSV, Excel or XML** with one click or via API, or connect **Zapier, Make, Slack, Google Sheets, webhooks** and the other platform integrations.

```bash
## Run via API and get JSON back
curl -X POST "https://api.apify.com/v2/acts/<ACTOR_ID>/run-sync-get-dataset-items?token=<YOUR_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"cities": ["Amsterdam"], "maxRentEur": 1200}'
```

### Data & fair use

- Only **publicly visible listing data** is collected — the same information any visitor sees.
- **No landlord or account data**: advertiser names, photos, IDs and activity are deliberately excluded (GDPR-conscious by design).
- Respectful request rates with modest concurrency; the actor reads Kamernet's lightweight page data rather than hammering search pages.
- Listing descriptions may contain whatever the advertiser wrote; treat them accordingly if you republish.

### FAQ

**Do I need proxies?** No — Kamernet currently works without any proxy. The input has a proxy option as a safety valve should that ever change.

**How fresh is the data?** It's scraped live at run time, directly from Kamernet's own page data — no caches, no third-party APIs.

**A run returned 0 items in monitoring mode — is that a bug?** No: it means nothing new appeared since the previous run for that search. That's the signal doing its job.

**City name doesn't work?** Use the Dutch spelling Kamernet uses (e.g. `Den Haag`, not `The Hague`). The actor logs a warning when a city page can't be found.

### Support

Found an issue or missing a field you need? Open an issue on the actor's **Issues tab** — it's monitored continuously and fixes usually ship within hours, not days.

# Actor input Schema

## `cities` (type: `array`):

One or more Dutch cities to search, e.g. <code>Amsterdam</code>, <code>Utrecht</code>, <code>Den Haag</code>. City names are converted to Kamernet slugs automatically.

## `listingTypes` (type: `array`):

Which property types to include. Leave empty for all types.

## `maxRentEur` (type: `integer`):

Only listings at or below this monthly rent. Kamernet filters in €100 steps; the value is rounded up to the next step (max €5,000).

## `minSizeM2` (type: `integer`):

Only listings with at least this surface area in m².

## `radiusKm` (type: `string`):

Radius around the city to include, in km. Kamernet supports up to 5 km.

## `sort` (type: `string`):

Order in which Kamernet returns listings (affects which listings are picked up first when <b>Max listings</b> caps the run).

## `maxListings` (type: `integer`):

Stop after this many listings (per run, across all cities). Keeps costs predictable.

## `fetchDetails` (type: `boolean`):

Visit each listing's page for the full record: description, exact address, postal code, GPS coordinates, deposit, agency fee, energy label, house rules and photos. Costs one extra request per listing; turn off for a fast, cheap overview.

## `newListingsOnly` (type: `boolean`):

Only output listings not seen in previous runs with the same search settings. Ideal on a schedule (e.g. every 30 min) to feed alerts — pair with a webhook or the platform's integrations.

## `language` (type: `string`):

Preferred language for title and description. Falls back to the other language when a listing has only one.

## `proxyConfiguration` (type: `object`):

Kamernet currently needs no proxy; leave as-is unless runs start failing.

## Actor input object example

```json
{
  "cities": [
    "Amsterdam"
  ],
  "listingTypes": [],
  "radiusKm": "5",
  "sort": "newest",
  "maxListings": 200,
  "fetchDetails": true,
  "newListingsOnly": false,
  "language": "en",
  "proxyConfiguration": {
    "useApifyProxy": false
  }
}
```
