# 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. REST and MCP. Every field carries its source, licence and currency date. Three-state honesty: has_value / checked_absent / not_checked - not_checked is NEVER a statement that a risk is absent. Base URL: https://agents.alphaquantlabs.ai Product: propertycheck-gold-coast Schema: 2026-10-01 Prices: agent-aud-v3 ## Coverage - City of Gold Coast local government area, Queensland, Australia only. Points outside are REFUSED (404 out_of_coverage), never answered with an all-clear. - Open government data only. No third-party commercial mapping content (no Google content) exists on any route, at any price. ## Fastest path: pay per lookup, no account (x402) GET https://agents.alphaquantlabs.ai/v1/property?lat=-27.9675&lng=153.4136 -> 402 + PAYMENT-REQUIRED (x402 v2, USDC on Base, A$1.39 incl. GST) Retry the same GET with the PAYMENT-SIGNATURE header your x402 client builds -> 200 + the envelope + PAYMENT-RESPONSE (transaction, receipt id). You are charged 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 (cheaper per lookup, 3 calls) 1. POST https://agents.alphaquantlabs.ai/v1/accounts {"email":"you@example.com","label":"my-agent"} -> api_key (shown once), 0 credits 2. POST https://agents.alphaquantlabs.ai/v1/credits/checkout Authorization: Bearer {"pack":"starter"} -> checkout_url (Stripe, for the human running you) or POST https://agents.alphaquantlabs.ai/v1/credits/x402 {"pack":"starter"} -> 402 + PAYMENT-REQUIRED (x402 v2, USDC on Base). Retry with PAYMENT-SIGNATURE from your x402 client -> credits, no human needed. 3. GET https://agents.alphaquantlabs.ai/v1/property?lat=-27.9675&lng=153.4136 Authorization: Bearer -> the envelope, 1 credit ## Free routes - GET /v1/health, GET /v1/blocks (catalogue + packs), GET /v1/schema (JSON Schema 2026-10-01), GET /llms.txt - GET /v1/openapi.json (OpenAPI 3.1, also at /openapi.json), GET /.well-known/agent-card.json (A2A Agent Card), GET /.well-known/x402 (x402 discovery) ## Paid routes (Authorization: Bearer ) - /v1/health : 0 credits - /v1/schema : 0 credits - /v1/blocks : 0 credits - /v1/account : 0 credits - /v1/property : 1 credit - GET /v1/account : balance, spend today, caps (free) - GET /v1/receipts : your tax receipts (free) - POST /v1/credits/x402 : buy a pack with USDC over x402 v2 (scheme exact, network eip155:8453). 402 first, then PAYMENT-SIGNATURE. Settled by facilitator; funds go straight to the operator's address. - POST /a2a : A2A JSON-RPC (SendMessage v1.0 or message/send v0.3), skill property_lookup, 1 credit; send a data part {"lat":..,"lng":..} - POST /v1/mcp : Model Context Protocol 2025-06-18, server "aql-propertycheck" (tools: propertycheck_lookup, propertycheck_catalogue, propertycheck_account). initialize, tools/list and propertycheck_catalogue work without a key; the lookup and account tools need one ## 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: on /v1/property. A replay returns the ORIGINAL envelope and is not charged again; x-aql-data-changed tells you if the sources have since moved. - Daily spend cap per account; burst and sustained rate limits (429 with retry-after). - Prices are AUD, GST inclusive.
