Key features

• 🏠 Annual WOZ valuations: export the source's annual valuations in wozValues, with latest value, valuation year and year-over-year changes.
• 📍 Dutch property addresses: search Dutch addresses or a whole street using street,city; export postcode, city and coordinates.
• 🗺️ Cadastral parcels: export the cadastral municipalities, sections and parcel numbers linked to each WOZ property.
• 🧱 Building characteristics: include construction year, floor area, purpose, building identity and residential-object count where published.
• 📈 Valuation growth: calculate annual growth and CAGR from the published valuation history, preserving missing values.
• 🔗 Paste-mode: use startUrls for WOZ property URLs with wozid or Kadaster address-search URLs. In query, mix supported URLs, WOZ IDs and addresses as a JSON list. Start URLs take precedence; duplicate properties are returned once.
• ♻️ Incremental mode: Track NEW, UPDATED and REAPPEARED properties between runs. Opt in to UNCHANGED rows or EXPIRED identity/timestamp rows; disappearance detection requires a complete scan and is suppressed when any property lookup fails.
• 🔔 Notifications: Telegram, Slack, Discord, WhatsApp Cloud API, and generic webhook out of the box. Pair with incremental for daily new-listing alerts without pipeline glue.
• 📦 Compact mode: AI-agent and MCP-friendly payloads with core fields only.
• 🔌 MCP connectors: export your results into Notion via Apify's MCP connectors — a clean run-summary page, no glue code. Opt-in via the App connector field; deterministic field-mapping, no AI. Built on Apify's connector framework, so more destinations open up as their catalog grows.
• 📤 Export anywhere: Download the dataset as JSON, CSV, or Excel from the Apify Console, or stream live via the Apify API and integrations (Make, Zapier, Google Sheets, n8n, …).

What data can you extract from wozwaardeloket.nl?

Each property contains its official address, WOZ object identity, published annual valuations, growth calculations and available location, cadastral and building data. WOZ values are tax valuations in EUR, not asking or sale prices. Description fields are readable summaries generated from these structured facts (plain text, HTML and Markdown), not source listing descriptions. Unavailable source fields remain null unless empty-field stripping is enabled. Compact mode keeps core fields. With emitExpired enabled, disappeared properties produce lifecycle rows with listingId, changeType, firstSeenAt, lastSeenAt and expiredAt; these do not contain a fresh property valuation.

Input

The main inputs are a search keyword, an optional location filter, and a result limit. Additional filters and options are available in the input schema.

Key parameters:

• query — Exact address (Kloosterlaan 33 1216NH, Kloosterlaan 33,Hilversum or 1216NH 33), or street,city for every property on a street. House letters/additions are matched exactly. JSON arrays or one address per line support bulk searches; supported property/search URLs and WOZ IDs can be included.
• location — Optional Dutch town, for example Amsterdam, Den Haag or Den Bosch. Combined with a street/address in query. Unknown places stop the run.
• maxResults — Maximum total results (0 = unlimited). (default: 100)
• startUrls — WOZ property URLs such as https://www.wozwaardeloket.nl/?wozid=036300163017 or Kadaster address search URLs. They replace query/location; results are merged and deduplicated. (default: [])
• incrementalMode — Compare against previous run state. stateKey is optional — defaults to a value derived from search inputs (queries, locations, startUrls, country) so different filter sets never share state. (default: false)
• emitUnchanged — In incremental mode, also export UNCHANGED properties. These delivered rows count toward maxResults and normal per-result charges. (default: false)
• emitExpired — In incremental mode, scan the full search universe and emit EXPIRED lifecycle rows (listingId and timestamps) for properties no longer present. Suppressed on partial/failed scans. Delivered lifecycle rows count toward maxResults and normal per-result charges. (default: false)
• includeDetails — Fetch full listing details. (default: true)
• compact — Core fields only (for AI-agent/MCP workflows). (default: false)
• descriptionFormat — Pick a single description representation. all keeps every variant; text / html / markdown drop the others. (default: "all")
• excludeEmptyFields — Drop null, empty-string, and empty-array fields from each record before push. Smaller payloads for AI agents and dashboards. (default: false)
• ...and 20 more parameters

Input examples

Basic search — Keyword-driven search with a result cap.

→ Full payload per result — all standard fields populated where the source provides them.

{
  "query": "Keizersgracht,Amsterdam",
  "maxResults": 50
}

Incremental tracking — Only emit properties that changed since the previous run with this stateKey.

→ First run builds the baseline state. Subsequent runs emit only records that are new or whose tracked content changed. Set emitUnchanged: true to include unchanged records as well.

{
  "query": "Keizersgracht,Amsterdam",
  "maxResults": 200,
  "incrementalMode": true,
  "stateKey": "keizersgracht,amsterdam-tracker"
}

Compact output for AI agents — Return only core fields for AI-agent and MCP workflows.

→ Small payload with the most important fields — ideal for piping into LLMs without token overhead.

{
  "query": "Keizersgracht,Amsterdam",
  "maxResults": 50,
  "compact": true
}

Output

Each run produces a dataset of structured property records. Results can be downloaded as JSON, CSV, or Excel from the Dataset tab in Apify Console.

Incremental fields

When incremental mode is on, each record also carries:

• changeType — one of NEW, UPDATED, UNCHANGED, REAPPEARED, EXPIRED. Default output covers NEW / UPDATED / REAPPEARED; set emitUnchanged: true or emitExpired: true to opt into the others.
• isRepost, repostOfId, repostDetectedAt — populated when a new listing matches the tracked content of a previously expired one. Set skipReposts: true to drop detected reposts from the output.

Exact and bulk address lookups

Use Kloosterlaan 33 1216NH, Kloosterlaan 33,Hilversum or 1216NH 33 for an exact lookup. Add a house letter or addition where applicable, such as 33A or 33-2; addresses with different suffixes are excluded. For bulk lookups, use a JSON list in query or one address per line. To export an entire street, leave out the house number: Kloosterlaan,Hilversum. A zero-match search returns no property rows. If an individual property cannot be read, the run retains other results, warns with WOZ-2010, saves incremental progress and suppresses disappearance detection. A run where all lookups fail is marked failed.
