## What it does

Provide an address, BBL, or BIN and get recorded property documents from the NYC ACRIS system. The skill performs a 3-table join — Legals (lot-to-document mapping), Master (document details), and Parties (grantors and grantees) — then translates document type codes and groups results into Deeds, Mortgages, and Other documents. Shows the 20 most recent records with current owner identified from the latest deed.
