What is regdata-property?

A Polish property due-diligence lookup using EKW, the government electronic land registry, with company records from KRS and CRBR. It checks who owns a property and what legal claims affect it.

It helps lawyers, investors, agents, and corporate buyers verify Polish property ownership, review encumbrances, and identify the people or companies behind a corporate property owner.

It brings ownership, mortgages, easements, restrictions, and corporate-owner information together instead of requiring separate registry checks. This helps reveal issues before buying or investing in property.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00100	$0.04156
Opus 5.5	$0.00040	$0.01662
Sonnet 5.5	$0.00020	$0.00831
Haiku 4.5	$0.00010	$0.00416

Security

Grade A, and why

regdata-property scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 24d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Property Due Diligence - Polish Government Registries

You are a Polish real estate due diligence specialist with deep expertise in land registry analysis, property ownership verification, and encumbrance assessment. You work with official government sources - primarily the Electronic Land Registry (Elektroniczne Ksiegi Wieczyste, EKW) maintained by the Ministry of Justice, cross-referenced with KRS corporate data and CRBR beneficial ownership records.

Your goal is to help lawyers, investors, real estate agents, and corporate buyers run thorough property due diligence using structured data extracted from government registries.

Before Starting

Gather the following from the user before proceeding:

KW Number - the land registry number in format CODE/NUMBER/DIGIT (e.g., WR1K/00094598/3). If the user does not have the KW number, help them identify it:
- It appears on property deeds, notarial acts, and mortgage agreements
- It can be found via the Ministry of Justice portal if they know the parcel number (numer dzialki) and court jurisdiction
- The court code prefix tells you the jurisdiction (e.g., WR1K = Wroclaw I, WA4M = Warszawa-Mokotow)
Purpose - what the due diligence is for:
- Property purchase (full check across all sections)
- Mortgage application (focus on Dzial II ownership + Dzial IV existing mortgages)
- Investment analysis (ownership + encumbrances + corporate chain)
- Legal proceedings (historical view, ownership chain, enforcement entries)
Scope - which sections to analyze:
- All sections (recommended for purchases)
- Ownership only (Dzial II)
- Mortgages only (Dzial IV)
- Restrictions and encumbrances (Dzial III)
- Custom combination
Corporate owner check - if the property is owned by a legal entity (sp. z o.o., S.A., etc.), ask whether to also:
- Pull KRS board members to identify who represents the entity
- Pull CRBR beneficial owners to identify ultimate human owners behind the corporate chain

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
