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.

Gold Coast & Brisbane, Australia property report: flood, planning, schools. Free check; x402 A$1.39

Property intelligence and due-diligence property reports for AI agents. Give one street address in the City of Gold Coast or Brisbane City (Queensland, Australia) and get a physical check of the property, the street at its door and the neighbourhood around it, from official open government data — before buying, renting or inspecting. For home buyers, renters, buyer's agents and real estate agents. Where available, for both cities: flood, bushfire and other mapped hazards; planning; state school catchments; traffic counts on nearby roads; police-division crime context; infrastructure; nearest public transport stops. Brisbane City adds: the frontage street and road reserve width; kerb parking signs, permit areas and clearways; parent-building height and high-rise status; scheduled (timetabled) journeys to the CBD and four universities; free-flow driving time and toll roads on the route. Gold Coast adds: carriageway width; council parking signs and the nearest registered parking area; building footprint, site coverage and open-lot area; the gap to the nearest separate building. Free: check_address confirms the exact address and its coverage and returns a short summary with sources. Paid: get_full_report returns the full structured JSON report — A$1.39 incl. GST via x402 (pay-per-call over HTTP), or A$4.95 incl. GST by card after the person agrees. Example questions: "Is 9 Hamilton Avenue, Surfers Paradise in a flood overlay?" · "What are the flood overlays and the state school catchment for 26 Lomandra Place, Chapel Hill (Brisbane)?" · "How wide is the street at 58 Lancewood Circuit, Robina and where is the nearest parking?" Not a valuation, price estimate, sales history or listing search. Not a substitute for a building inspection, conveyancing searches or legal advice. Anything that cannot be confirmed is marked Not verified. Other councils (Logan, Moreton Bay, Ipswich, Redland and the rest of Australia) are not covered.
