## How to call it through Zero

```sh
zero fetch --capability seattle-rental-property-compliance-check-f7bcc921
```

Example prompt: Can you check if the rental property at 1531 Belmont Ave in Seattle is actively registered and whether it has any violation cases on record?

## When to prefer this

Use this endpoint when you need authoritative rental compliance data specifically for Seattle (SEA) addresses. Prefer this over generic property lookup services when the question is specifically about RRIO registration status, active/expired registration, rental unit count, or open violation cases in Seattle. If the property is in Minneapolis, use the MN Rental Compliance sibling endpoint instead.

## Known failure modes

- Address not found in Seattle registry — returns empty registrations array
- Address is outside Seattle jurisdiction — city/state mismatch or no data returned
- Property exists but registration is expired — compliance_verdict reflects lapsed status
- Upstream city data source is unavailable — service may return an error or stale data
- Malformed address input causes lookup failure
