“AQL PropertyCheck — Physical check of one exact address” is shared by 3 different URLs
All exact-name matches are shown; ranked results follow.-
AQL PropertyCheck checks the physical context of one exact address. Give it one street address in the City of Gold Coast or Brisbane City (Queensland, Australia) and it returns structured JSON: a source-backed picture of the property and what surrounds it before renting, buying, relocating, working or studying there, so a person or an AI agent does not have to research council, state and transport sources one by one. Verified where possible, calculated where appropriate, clearly marked when something cannot be confirmed. It is not a property valuation or investment forecast. Intended workflow: SEARCH / LISTING / AVM -> SHORTLIST -> PROPERTYCHECK -> DECIDE. Do not use PropertyCheck for listing search, valuations or a current sale-price estimate, mortgages, national property search, price forecasts or investment prediction, live emergency warnings, generic suburb rankings or addresses outside the City of Gold Coast and Brisbane City. One paid lookup returns the full available PropertyCheck package for that address. Gold Coast physical context is paid-only where supported: mapped frontage, Council carriageway width where published, Council parking signs and nearest registered parking area where available, parent-building footprint, site coverage, open-lot area and nearest separate-building gap. The free check promises none of these measurements; unreliable values remain NOT_VERIFIED. Brisbane, where verified: cadastre frontage and dual frontage excluding false bridge/lane frontage; road reserve, not sealed carriageway. Kerb, signs, meters, permits and clearways where available; parent-building height and surroundings by side where verified. Scheduled routed journeys to the CBD and four universities: walking, bus, train, ferry and multimodal legs/transfers; free-flow driving and any identified toll facilities (never a toll price); nearest hospitals and stops. Floors and tower-to-tower gaps remain unverified. Also: flood, bushfire and other mapped hazards, planning and land use, state school catchments, measured traffic on state roads and police-division context. Structured JSON with source and status where available. Check coverage first. Via MCP, Agent JSON costs A$1.39 via x402 or A$4.95 by human-approved card; A2A requires an existing API key. The consumer PDF is separate. Open data only; no Google content.
