## 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 locus-fair-market-rents-property-scan-a7496e08 -d '<json body>'
```

Example prompt: Can you run an early property scan on 123 Main Street, Austin TX 78701 and tell me about any local records, parcel rules, or risk signals that might affect its use or value?

## When to prefer this

Use this endpoint when you need a quick, low-cost property intelligence scan covering local public records, zoning/parcel rules, and risk signals for a US address or ZIP code — particularly useful for pre-purchase due diligence, rental pricing research, or identifying regulatory constraints before committing to a property.

## Known failure modes

- Invalid or unrecognized US address returns empty records array
- Missing both address and zip fields returns a validation error
- Non-US addresses are not supported
- ZIP code too vague to return parcel-level detail — results may be zip-level only
- Payment failure (x402) prevents scan from running
- Service may return empty records if no local data is indexed for that area

## How this service works

HUD Fair Market Rents by county. Perfect for: 'fair market rent for a county', 'HUD FMR lookup', 'voucher rent limits', 'Section 8 rent standards', 'program rent for an area'. Returns official HUD Fair Market Rents (efficiency through 4-bedroom) for a US county by fiscal year from the HUD USER API. National. Program rent context only -- not market listings or affordability advice. Charge-free when the HUD token is not configured or the HUD API is unavailable.

## Output

A JSON object containing a scan ID, generated timestamp, any relevant property records, parcel rules, or risk signals found for the given address or ZIP code, plus caveats about data freshness or completeness.
