Use cases llm-inferred: Due diligence: find parcels owned by a named person or company in a covered US county before a site visit · Pull the official county parcel endpoint and APN/address fields for a US site assessment · Locate city permit, code-violation or zoning-case datasets for a US street address
Audience llm-inferred: GIS analysts · planners · due diligence analysts

Constraints llm-inferred: US counties only; not relevant to UK projects · Owner-name search only where the county publishes a searchable owner field; some counties are APN-only or location-only · Never executes queries or returns parcel records; the user must fetch the returned URLs · 412 of 413 endpoints are live; county services can change or go offline · Package is version 0.x and pre-1.0, so the interface may change · City dataset lookups are limited to covered cities and city limits, and hold no owner data · Socrata throttles anonymous callers; a custom app token is needed for volume
