# Property Check

`GET /api/public/v1/property-check`

## Request

- Base URL: `https://api.casaintelligence.com.au` (the document declares no server; this is the origin it was published from)

Indicative planning & development intelligence for a SEQ property.

Deterministic (no AI in the hot path), cached, and rate-limited. Returns
zone, overlays, an indicative development/subdivision outlook + Casa score,
and aggregate nearby-DA activity. **Indicative only — not planning advice and
not a guarantee of approval.** For the definitive answer, order the $199
Preliminary Planning Report (see `confirm.url`).

## Query parameters

- `address` string, required: Property address to check (SEQ).
- `lat` number, nullable: Optional geocoder latitude.
