```

Example prompt: Can you run a Locus early property scan on 742 Evergreen Terrace, Springfield, IL 62704 and tell me about any zoning rules, risk signals, or local record issues that could affect its use or value?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.05) early-stage property intelligence scan covering parcel rules, zoning signals, and risk factors for a US property — particularly useful before deeper due diligence, when evaluating a property for purchase, investment, or development planning.

## Known failure modes

- Missing both address and ZIP code — returns validation error
- Invalid or unrecognized US address — may return empty records array
- Non-US location provided — not supported, likely returns empty or error
- Payment failure (x402) — call not processed
- Parcel data unavailable for rural or sparse coverage areas — empty records
- Rate limiting or service downtime — HTTP 5xx error

## How this service works

Census housing-stock context for an area. Perfect for: 'housing stock for an area', 'how old are the homes / median year built', 'owner vs renter share', 'housing units and vacancy for a place'. Returns cited ACS housing-stock characteristics (units, age, tenure, vacancy) for the resolved county/area. National. Area-level context, not a parcel record. Charge-free when the housing-stock lookup fails.

## Output

A JSON object containing a scan ID, generated timestamp, a list of records from local parcel data and risk signals, and any caveats about the data — covering factors that may affect the property's permitted use, costs, development plans, or future value.
