# AQL PropertyCheck

> AQL PropertyCheck is a paid API for AI agents from agents.alphaquantlabs.ai, paid per call via x402, $0.978874/call, status unknown (last checked 2026-10-29).

Looks up a single Australian property by lat/lng coordinates and returns live coverage data including planning constraints, school zones, and other open-government property attributes.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aql-propertycheck-969ba4eb
```

Example prompt: Can you check what planning blocks, school zones, and any hidden issues apply to the property at latitude -27.9675, longitude 153.4136 in Australia?

## When to prefer this

Choose this endpoint when you need live, open-government property constraint data for a specific Australian coordinate — particularly when you need school zone, planning block, or hidden-issue checks with explicit coverage confirmation and redistribution rights. Prefer this over generic geocoding or address APIs when the use case specifically requires Australian planning or zoning data tied to precise GPS coordinates.

## Known failure modes

- Coordinates outside Australian coverage area returns in_coverage: false
- Missing required lat or lng parameters returns a 400-level error
- Coordinates in a covered area but with withheld blocks returns partial data with withheld array populated
- Malformed coordinate strings (non-numeric) likely return a validation error
- Payment failure (x402) returns a 402 Payment Required before data is delivered

## How this service works

AQL PropertyCheck full report for one City of Gold Coast or Brisbane City address: the property and what surrounds it, with source and status where supplied by the result. Coverage is checked before any charge. Not a valuation.

## Output

Returns a JSON object with: coverage status (whether the coordinates are within the service area), a blocks dictionary showing checked planning constraints (e.g. school zones, hidden-issues-v6) with state values like 'has_value' or 'checked_absent', a withheld array listing any data blocks that couldn't be returned with reasons, redistribution rights, the product name, input coordinates echo, and a schema version timestamp.
