summary: Property Code-Violation & Lien History (Open-Data Cities)
description: 'Before buying, leasing or insuring a US property, reads the city''s own open-data code-enforcement records for one address (or a NYC BBL/BIN) and returns normalized violations with date opened, category, description, open/closed status, source severity class and record URL; deterministic counts by status, category and year; days since the latest violation; the longest repeat-citation streak (citations within 90 days of each other); and a rule-based distress indicator (none/watch/elevated) with every rule, value and threshold shown (open_records 1/5, open_hazardous 1/3, recent_records 3/10, repeat_streak 3/6, lien_listings 1/2). NYC also reads DOB/ECB summonses and the DOF tax/water lien sale list by tax lot. Covered cities: New York City, NY, Chicago, IL, San Francisco, CA, Seattle, WA, Austin, TX, Los Angeles, CA, Philadelphia, PA, Boston, MA. An uncovered city is rejected with the supported list before payment. Addresses are normalized and matched on number, direction, street and type; differently written streets are reported but never merged, and ambiguous matches return INSUFFICIENT_DATA. No LLM. Reports public records only: not ownership, title or legal advice; no alerts; private records and county tax-lien sales are not checked, and lien data is covered only for NYC.
Price: 0.05 USDC on Base (x402).'
