AQL PropertyCheck — check one exact address (Gold Coast & Brisbane)
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. 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. Available over MCP and REST. Live geographic coverage comes from the canonical PropertyCheck registry. Source, status, licence and date appear where supplied by the underlying result.
propertycheck/2 JSON from check_address and get_full_report uses six statuses: VERIFIED, CALCULATED, CONDITIONAL, NOT_VERIFIED, NOT_APPLICABLE and WITHHELD, with a reason_code. NOT_VERIFIED is unknown, never a statement that a risk is absent. The REST /v1/property route keeps its region-native states (Gold Coast has_value / checked_absent / not_checked; Brisbane seven declared states). Points outside the coverage area are refused, not answered with an all-clear.Quickstart: five minutes, no key, nothing charged
MCP protocol versions 2025-03-26, 2025-06-18, 2025-11-25 (stateless, so initialize is optional) and 2026-07-28 (server/discover, no handshake). The commands below are the 2025 form.
1. List the tools
curl -s https://agents.alphaquantlabs.ai/v1/mcp -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'2. Free check of one address: findings with status and source
curl -s https://agents.alphaquantlabs.ai/v1/mcp -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"check_address","arguments":{"address":"26 Lomandra Place, Chapel Hill QLD 4069"}}}'3. Ask for the full report: nothing is charged; the answer is an x402 PaymentRequired offer (A$1.39 incl. GST in USDC on Base, Polygon or Solana; isError stays true until paid). An x402 client signs one of the offers and repeats the call with params._meta['x402/payment']. Without a wallet, ask the person first, then call with payment_method: "card" (A$4.95 incl. GST, a Stripe checkout link for the person; poll with purchase_id and access_token).
curl -s https://agents.alphaquantlabs.ai/v1/mcp -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"get_full_report","arguments":{"address":"26 Lomandra Place, Chapel Hill QLD 4069"}}}'A street number is required. A suburb on its own, or an apartment whose unit cannot be verified on the official record, is refused with what to send instead; an address outside the City of Gold Coast and Brisbane City is answered as outside coverage and never charged.
One-off Agent JSON: pay per lookup, no account
GET /v1/property?lat=…&lng=… with no key answers 402 and a PAYMENT-REQUIRED header (x402 v2, USDC on Base, Polygon or Solana, A$1.39 incl. GST). Retry with the PAYMENT-SIGNATURE your x402 client builds and the envelope comes back with a PAYMENT-RESPONSE. You pay only when a full envelope is served — an outage on our side or a point outside the coverage area is never settled.
Existing B2B API-key accounts
Existing account and credit-based integrations continue to work through /v1/property and /a2a. Use the owning API key and a stable Idempotency-Key for a lookup; retries do not debit twice. An API key is not needed to start with free check_address or buy one Agent JSON report through MCP.
Business API
POST /v1/reports creates one immutable report with a required idempotency key. Scoped credentials separate report generation, retrieval, billing and key management. Reports are tenant-isolated and retrieval never charges again.
MCP
Protocol 2025-11-25, server aql-propertycheck. Public tools: check_address (free summary) and get_full_report (API key, x402, or human-approved A$4.95 Stripe checkout for a wallet-less user). Earlier tools stay callable by name for existing integrations. Same report and money code as REST.

| Block | What it answers | Licence |
|---|---|---|
coverage | Whether the queried point falls inside the serviced local government area, and the planning zone at that point. | CC-BY-4.0-AU |
property-context | Planning zone, precinct and mapped maximum building height at the queried point. | CC-BY-4.0-AU |
hidden-issues-v6 | Mapped flood, bushfire hazard, transport noise corridor, major electricity infrastructure and road-widening constraints. | CC-BY-4.0-AU |
land-use | Queensland land use classification at the queried point. | CC-BY-4.0-AU |
schools | State primary and secondary school catchments containing the queried point. | CC-BY-4.0 |
transport | Nearest scheduled bus, train and tram stops with straight-line distance. | CC-BY-4.0-AU |
police-division | Police division containing the queried point. Division level, never address level. Division-level context only. It describes the police division, not this address. | CC-BY-3.0-AU |
traffic | Measured traffic volume by hour of day and day of week on nearby counted roads. | CC-BY-4.0-AU |
roadworks | Withheld — The consumer product currently reads this from the QLDTraffic web page rather than the official API. A scraped page carries no licence grant we can point an API customer at. This block becomes sellable only after migration to the official QLDTraffic v2 API with our own key, which is published under CC BY 4.0. | — |

Agent JSON prices
- Autonomous x402: A$1.39 incl. GST for one full Agent JSON report.
- Human-approved card checkout: A$4.95 incl. GST for the same Agent JSON report through
get_full_report.
Price table agent-aud-v4. The A$17.95 consumer PDF is a separate website product, not the Agent JSON price. B2B receipts are tax documents at GET /v1/receipts.
Money rules
- Existing B2B account balances are reserved before a keyed lookup and refunded if our side fails or the point is out of coverage. You are never charged for our failure.
- Send
Idempotency-Key. A replay returns the original envelope without a second charge;x-aql-data-changedsays whether the sources have since moved. - A daily spend cap protects you from your own runaway loop; burst and sustained rate limits protect the public data sources (
