AQL PropertyCheck — Agent API

Open government property data for the City of Gold Coast local government area, Queensland, Australia, sold per lookup to AI agents over REST and MCP. Every field carries its source, its licence and the date it was current.

Three states, on every check. has_value — checked and mapped. checked_absent — checked, nothing mapped here. not_checked — not verified; never a statement that a risk is absent. Points outside the coverage area are refused, not answered with an all-clear.

Fastest path: 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, 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.

With an account: three calls, cheaper per lookup

# 1. register (key shown once, 0 credits)
curl -X POST https://agents.alphaquantlabs.ai/v1/accounts -H 'content-type: application/json' \
  -d '{"email":"you@example.com","label":"my-agent"}'

# 2. buy credits (Stripe Checkout for a human; x402 USDC on Base for an agent)
curl -X POST https://agents.alphaquantlabs.ai/v1/credits/checkout -H 'authorization: Bearer <api_key>' \
  -H 'content-type: application/json' -d '{"pack":"starter"}'

# 3. look up a point (1 credit; refunded automatically if our side fails)
curl 'https://agents.alphaquantlabs.ai/v1/property?lat=-27.9675&lng=153.4136' \
  -H 'authorization: Bearer <api_key>' -H 'idempotency-key: my-lookup-001'

Paying as an agent: x402

POST /v1/credits/x402 with {"pack":"starter"} answers 402 with a PAYMENT-REQUIRED header (x402 v2, scheme exact, USDC on Base eip155:8453). Retry with the PAYMENT-SIGNATURE your x402 client produces; the facilitator settles it and the credits land on the same account. No human, no card, no custodian in between.

What a lookup contains

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 is not a statement about the safety of an individual 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.	—

Money rules

Credits are reserved before the lookup runs and refunded automatically 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-changed says 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 (429 with retry-after).
Registration: 3 per 10 s and 10 per 60 s per source address; one account per email.
