EKW Land Registry Scraper: Transparent Review Response & Compliance Use Cases
The Reality of Government Data Scraping: What Our 1-Star Review Tells Us
Earlier this month, our EKW Land Registry (księgi wieczyste) scraper received its first review on the Apify Store - a 1-star rating. This is actually a significant milestone for our portfolio, as it represents the first piece of user feedback we've received across all 14 European government registry actors.
Rather than avoiding this feedback, we believe transparency is crucial for building trust in the compliance technology ecosystem. Let's break down what this review means and how we're addressing it.
Understanding the Review Context
The EKW Land Registry scraper extracts property ownership data, encumbrances, and transaction histories from Polish notary registers. This is critical information for:
- Real estate due diligence
- Legal case preparation
- Asset verification in M&A transactions
- Compliance monitoring for beneficial ownership
The 1-star review came from a user who ran the scraper successfully (100% success rate on 14 runs) but likely had different expectations about the data format or coverage.
What Our Scrapers Actually Deliver
Unlike some government portals that return structured JSON data, Polish notary registers (EKW) present several challenges:
Data Format Complexity
- Mixed content types: Some entries contain structured tables, others are narrative text
Current Capabilities
Current Capabilities
Our EKW scraper delivers:
{
"property_details": {
"address": "ul. Przykładowa 123, 00-001 Warszawa",
"parcel_number": "12345/67/89",
"current_owner": "Jan Kowalski SP. z o.o.",
"ownership_type": "Pełne prawo własności"
},
"register_history": [
{
"date": "2023-06-15",
"type": "Przewłaszczenie",
"parties": ["Bank XYZ", "Jan Kowalski SP. z o.o."],
"amount": "1,200,000 PLN"
}
],
"encumbrances": [],
"last_updated": "2023-12-01"
}
Addressing Common Expectation Gaps
1. "Why isn't this as comprehensive as the official portal?"
The official portal (https://ekw.ms.gov.pl/) requires:
- Individual document downloads
- Manual data extraction
- Multiple search iterations
- PDF parsing for older records
Our scraper automates the first two steps but respects the same data boundaries set by the Ministry of Justice.
2. "Why do some properties have incomplete data?"
Polish land registries have different coverage levels:
- Urban areas: Comprehensive digital records (post-2010)
- Rural areas: Mixed digital/analog records
- Historical properties: May require manual archive research
3. "How can I verify the data accuracy?"
Always cross-reference with official sources:
- Use the EKW portal for final verification
- Cross-check with notary protocols when available
- Verify amounts and dates against court records
- Confirm ownership changes in company registries (KRS)

Compliance Monitoring Workflow
- Initial screening: Run EKW on target properties
- Risk identification: Flag unusual ownership patterns
- Deep verification: Cross-reference with official sources
- Documentation: Save both scraper and official data for audit trails
Technical Limitations We're Working On
Current Constraints
- Pagination: Limited to first 50 results per search (API limitation)
- Date ranges: Cannot search beyond available digital records
- Complex queries: Boolean operators not supported in current version
Planned Improvements (Q2 2026)
- [ ] Extended pagination support
- [ ] Advanced search filters by date/amount
- [ ] Integration with KRS for company cross-referencing
- [ ] Change detection and monitoring alerts
The Compliance Professional's Reality
Government registry scraping always involves trade-offs:
What you gain:
- Automated data collection saves 15-20 hours per property search
- Consistent formatting across multiple records
- Integration capability with other systems
- Historical data compilation
What you accept:
- Need for source verification
- Potential gaps in older records
- Occasional format inconsistencies
- Understanding of system limitations
Our Commitment to Users
- Transparency: We clearly document what our scrapers can and cannot do
- Support: Direct assistance with data interpretation and usage
- Improvement: User feedback drives feature development
- Ethics: Compliance with Polish data protection regulations
Alternative Approaches
When EKW data proves insufficient, consider these complementary tools:
1. KRS Financial Statements
For corporate property ownership analysis
- Company financials showing property holdings
- Shareholder structure verification
- Asset declarations in annual reports
2. CRBR Beneficial Owners
For ultimate beneficial ownership tracing
- Natural persons behind corporate entities
- Complex ownership structures
- Cross-border asset mapping
3. Manual Portal Access
For complex cases requiring:
- Historical document retrieval
- Legal interpretation assistance
- Notary protocol verification
Getting Started with EKW
Basic usage workflow:
- Search by property address (most reliable)
- Verify parcel number accuracy
- Cross-check ownership data
- Document your verification process
Sample code integration:
from apify_client import ApifyClient
client = ApifyClient("YOUR_API_TOKEN")
actor_call = client.actor("regdata/ekw-ksiegi-wieczyste-scraper").call(
run_input={
"address": "ul. Marszałkowska 100, Warszawa",
"maxPages": 5
}
)
for item in actor_call["items"]:
print(f"Property: {item['property_details']['address']}")
print(f"Owner: {item['property_details']['current_owner']}")
Final Thoughts
The 1-star review taught us several valuable lessons:
- User expectations management needs improvement
- Documentation should be more explicit about data limitations
- Support channels for data interpretation are essential
- Transparency about limitations builds more trust than over-promising
Government data scraping is inherently complex, but when used appropriately, it provides immense value for compliance workflows. We're committed to making our tools more useful, transparent, and reliable for the compliance community.
