Poland EKW Land Registry Scraper | Elektroniczne Ksiegi Wieczyste

Extract property data from Poland's Electronic Land Registry (Elektroniczne Ksiegi Wieczyste, EKW) - ownership, mortgages, restrictions, and encumbrances - as structured JSON. Provide a KW number and get all five sections of the land-and-mortgage register back, in bulk, beyond what the portal's one-KW-at-a-time manual lookup allows.

No login, no API key, no proxy, nothing to configure - just provide your KW numbers and run.

What data do you get?

One record per property, split into the register's official sections:

How much does the EKW data cost?

Pay per result - you are not charged for Apify platform usage, only a fixed price per property. The price drops on higher Apify subscription tiers.

Volume	Cost
1 property	$0.01
100 properties	~$1.03
1,000 properties	~$10.03
10,000 properties	~$100.03

Plus a $0.025 start fee per run. Free plan: Apify Free-plan users get a preview allowance of 25 KW numbers per 30 days; the run exits gracefully with a status message when the allowance is reached (it never fails or hides results). Upgrade to any paid Apify plan for unlimited batches.

Is it legal, and where does the data come from?

Data comes from the official EKW portal at przegladarka-ekw.ms.gov.pl, operated by Poland's Ministry of Justice under the Land and Mortgage Register Act (Ustawa o ksiegach wieczystych i hipotece). The register is public (~25 million property entries across all Polish courts). Extraction of this public data is permitted; note that the register contains personal data (owner names, and sometimes PESEL) - you are responsible for lawful, GDPR-compliant use downstream.

How do I use it?

Click Try it and paste this input:

{ "kwNumbers": ["WR1K/00094598/3"] }

A KW number is CODE/NUMBER/DIGIT - the 4-char court code, the 8-digit register number, and a check digit (which is auto-calculated if you omit it). Pass many numbers in kwNumbers, and use sections to fetch only the parts you need.

Input options

Parameter	Type	Required	Default	Description
kwNumbers	string[]	Yes	-	KW numbers CODE/NUMBER/DIGIT (e.g. WR1K/00094598/3). Check digit optional.
viewType	string	No	aktualna	aktualna = current, zupelna = full history, dotychczasowa = legacy format
sections	string[]	No	all	Which sections: IO, ISp, II, III, IV
includeRawHtml	boolean	No	false	Include raw HTML of each section

What you can do with it

• Real-estate due diligence - verify ownership, mortgages, and restrictions before a purchase or a deal.
• Mortgage & collateral verification - check existing liens and encumbrances (Dzial IV) on a property before lending.
• Ownership lookup - find who owns a specific property and their share (Dzial II).
• Legal research - review easements, caveats, and court orders affecting a property (Dzial III).
• Enforcement - check the property status of a debtor as part of collection or bankruptcy work.

Run it from code

# cURL - start a run and get the dataset back
curl -X POST "https://api.apify.com/v2/acts/regdata~ekw-ksiegi-wieczyste-scraper/run-sync-get-dataset-items?token=YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "kwNumbers": ["WR1K/00094598/3"] }'

// Node.js - apify-client
import { ApifyClient } from 'apify-client';
const client = new ApifyClient({ token: 'YOUR_TOKEN' });
const run = await client.actor('regdata/ekw-ksiegi-wieczyste-scraper').call({ kwNumbers: ['WR1K/00094598/3'] });
const { items } = await client.dataset(run.defaultDatasetId).listItems();

# Python - apify-client
from apify_client import ApifyClient
client = ApifyClient("YOUR_TOKEN")
run = client.actor("regdata/ekw-ksiegi-wieczyste-scraper").call(run_input={"kwNumbers": ["WR1K/00094598/3"]})
items = client.dataset(run["defaultDatasetId"]).list_items().items

FAQ

Is it legal to scrape EKW? Yes. The land register is public under the Land and Mortgage Register Act. Extraction of public data is permitted; because the register contains personal data, you remain responsible for lawful, GDPR-compliant use downstream.

Do I need an account, API key, or proxy? No - none of them. Just provide the KW numbers and run it; you only need an Apify account.

What if I don't know the check digit? Omit it. Provide CODE/NUMBER and the check digit is calculated automatically.

Does it return PESEL numbers? The register itself sometimes contains PESEL in the owner entries, and raw values are not filtered out. Handle that personal data in line with GDPR, and use sections to fetch only what you need.

Current state vs full history? viewType: "aktualna" (default) returns the current content; "zupelna" returns the complete history; "dotychczasowa" returns the legacy format.

What export formats are supported? JSON, CSV, Excel, or XML, or read live via the API.

Limitations

• The register contains personal data (owner names, sometimes PESEL); raw PESEL values are not filtered - you must handle GDPR compliance.
• Each KW is fetched individually, so large batches take proportionally longer.
• Some legacy or unusual register layouts may parse less completely; enable includeRawHtml to keep the source.
