Limitations

What it does not do

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.

FAQ

Does EKW have an API?

EKW (Poland) does not offer a clean public API for programmatic queries. getregdata reads the official source directly and returns structured JSON, keyed off the KW identifier - so you get API-like access without an official endpoint.

How do I get EKW data programmatically?

Install the getregdata agent skills or MCP server, or run the regdata/ekw-ksiegi-wieczyste-scraper actor on Apify. Query by KW or company name and receive structured, source-attributed records. It is free to install; you pay per result on Apify.

What data does EKW return?

Ownership and mortgage entries from the electronic land and mortgage register.
