🟢lookup_property(address, borough, zip)
Resolve a free-text NYC address to its tax lot (BBL) and return the property facts: summary, owner of record, building, assessment, last priced deed and open-item counts. Returns the best match with a 0-1 confidence, a plain-English confidence_explanation, a machine-readable match_type, the HTML/Markdown/JSON URLs and up to 4 alternatives. Requires "address". Use get_property for a known BBL/BIN.
