PropertyCheck checks the building, neighbouring sites, street, access and everyday journeys for one exact address in Brisbane City or the City of Gold Coast. It combines official and licensed sources with calculated measurements where available. Brisbane may include past mapped floods and timetabled CBD or university journeys; Gold Coast may include Council carriageway width and whole-building measurements. A free check establishes coverage and a short summary; paid Agent JSON adds conditional detail with statuses, source references and data dates where supplied. No account is required for a one-off report.
For an AI workflow that needs the full structured report, connect to the JSON tools: check_address is free; get_full_report offers payment and returns the JSON after confirmed payment. No API key or account is required for a one-off purchase.

A$1.39 incl. GST via x402 with a compatible funded wallet, or A$4.95 incl. GST by card after the person agrees. Receiving an offer does not charge anything.
For ChatGPT environments that support custom MCP connectors:

Free address check; full Agent JSON A$4.95 incl. GST by card with human consent. This is a separate custom connection, not the published free ChatGPT app.
Developer quickstart, five minutes, no key: copy-paste curl calls for tools/list, a free check_address and the unpaid get_full_report offer (nothing is charged) are on the Agent documentation page. MCP protocol versions 2025-03-26, 2025-06-18 and 2025-11-25; a street number is required.
Agent JSON is a separate product from the consumer PDF. The free assistant connector /v1/connect does not provide get_full_report or sell Agent JSON. See the purchase steps.
No key, no payment. Checks address identity and coverage, flags an unverified unit where applicable, and returns a short summary.
incl. GST, paid per call in USDC (Base, Polygon or Solana). No account. get_full_report
incl. GST, only after the person agrees. The agent hands the person a checkout link, then collects the JSON.
Coverage is checked before any charge. An address outside the City of Gold Coast or Brisbane City is refused and never charged. Existing business API-key accounts keep their own terms.
Custom MCP in ChatGPT: where your environment supports it, add a custom MCP connector using the card-only URL below. The address check is free. For a full Agent JSON report, the assistant asks first, then gives the person a card checkout link for A$4.95 incl. GST. It retrieves the JSON after payment is confirmed. This custom connection is separate from the free published app.

No sign-in. This connector does not offer the paid JSON tool. If you need structured JSON, use the Agent JSON connection above.
Consumer PDF on the website: free address preview; full PDF A$17.95 incl. GST for supported addresses. This is a separate website purchase, not an Agent JSON report.
What can change after the free check? These same-address comparisons are from an isolated Agent contract 2.1.0 test on 20 October 2026 using recorded official-data packages. They are not independently verified current Production paid responses or customer purchases. Values and availability can change with source updates; a purchase does not guarantee a measurement.
Free in the test: Complex and planning context; Council flood/bushfire map result; nearby light rail.
Full Agent JSON in the test: Parent-building footprint, site coverage and open-lot calculation from Queensland building outlines and Council lot data; Council carriageway and parking-sign context where available.
Limit: These measurements describe the building/site, not unit 1902. Nearest-building gap and frontage length were NOT_VERIFIED; health and area sections had no values in this test.
Free in the test: Mapped historical flood and complex context; approximate parent-building height.
Full Agent JSON in the test: Registered unit lot and parent-building measurements from Queensland LiDAR/building outlines; building context by side, road-reserve and kerb context, and modelled journeys in this test. Journey legs and transfers may be available with detail: "full".
Limit: Building facts do not establish a floor-specific or unobstructed view. Carriageway width and tower-to-tower gap were NOT_VERIFIED; 2019 LiDAR is not a live building survey.
Crime figures in these Agent JSON examples are police-division context, not 250/500 m counts around a home. Some sections can be empty or WITHHELD. A paid report does not turn unknowns into verified facts.
Free check (check_address) | Full report (get_full_report) | |
|---|---|---|
| What you get | Address match or its stated limit, coverage, a short summary | Up to twelve named sections with item statuses and sources or dates where supplied; usable values depend on the address and source data |
| Use it for | Is this address covered? A first look. | Due diligence on a shortlisted property |
| Price | Free, no key | A$1.39 incl. GST via x402, or A$4.95 incl. GST by card after the person agrees |
The contract defines twelve sections, but an individual address may have fewer usable values. Items report verification status and source references where supplied; absent and withheld facts are not sold as verified. Availability depends on city and address.
| Section | Examples |
|---|---|
| Hazards | Council flood mapping and past flood extents, bushfire, landslide, coastal erosion, power lines, heritage, acid sulfate soils |
| Planning & property | Planning zone, neighbourhood plan, land use around the lot, lot/plan, land area, tenure, strata status |
| Education | State primary and secondary school catchments, distance to the nearest state schools |
| Street, parking & traffic | Street type, road reserve or carriageway width, Council parking signs and clearways, nearest counted road and weekday traffic, transport noise |
| Getting around | Nearest stops; in Brisbane, timetabled journeys to the CBD and four university campuses, departures nearby, toll roads on the driving route |
| Building & surroundings | Gold Coast: building footprint and site coverage where calculated; gap to the nearest separate building only where verified. Brisbane: parent-building height and high-rise status where verified |
| Safety, health, change, area | Police-division context and five-year trend, nearest public hospital, planned roads and major works, population, households, tenure mix and income for the area |
Not a valuation, price estimate, sales history or listing search. Not a substitute for a building inspection, conveyancing searches or legal advice. NOT_VERIFIED always means unknown — never clear or absent.
