## 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-free-early-property-scan-96df7a49 -d '<json body>'
```

Example prompt: Can you run an early property scan on 742 Evergreen Terrace, Springfield, IL using Locus — I want to see any local records, zoning rules, or risk signals that might affect what I can do with it or what it's worth?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.05) preliminary property intelligence scan before committing to a full property report — ideal for early due diligence on a US address or ZIP code to surface zoning rules, public records, and risk signals.

## Known failure modes

- Invalid or unrecognized address returns empty records array
- ZIP code only may produce less precise parcel-level results
- Payment not received (402) blocks the response
- Malformed input schema returns validation error
- Property not found in local record databases returns minimal or empty results

## How this service works

Recorded-sale comparables for one US address or point: comp rows (parcel, site address, sale date, price, and price per land square foot where lot acreage is published) within 1500m over 24 months, plus median price, price range, and a coarse up/flat/down trend. From official county assessor/parcel records; arithmetic only, never owner/buyer/seller, never a valuation or AVM. A thin area returns a free charge-suppressed diagnostic. npx @velinussage/locus-agent-skill add.

## Output

A JSON object with a report ID, list of records (local records, parcel rules, risk signals), generation timestamp, and any caveats about data completeness or reliability.
