# Locus: Property Scan

> Locus: Property Scan is a paid API for AI agents from api.locus.report, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

## 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-property-scan-154ac262 -d '<json body>'
```

Example prompt: Can you run a Locus property scan on 742 Evergreen Terrace, Springfield, IL — look back 90 days, search within 500 meters, and include any nearby incidents?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01) property intelligence snapshot covering local records, parcel rules, and risk signals for a specific address — especially when evaluating real estate, planning renovations, assessing neighborhood risk, or doing pre-purchase due diligence. Prefer this over general web search when structured parcel and incident data is needed.

## Known failure modes

- Address too short or unrecognized — validation error returned
- No records found for the given address in the lookback window — empty records array
- Invalid radius or lookback values — schema validation error
- Payment not completed — 402 response blocking access
- Upstream data source unavailable — partial or empty result with caveats

## How this service works

Recorded sale price and assessed value for a specific parcel, cited to the county source. Perfect for: 'last sale price for this address', 'assessed value of this property', 'tax roll value of this parcel', 'owner of record value' (Locus returns assessor value facts, never owner names). Third-party public assessor facts only; Locus does not appraise, estimate market value, rank, or score. Charge-free unless a verified source returns a sale price or assessed value.

## Output

A JSON object with a scan ID, list of local records and parcel rules affecting the property, risk signals, and a timestamp of when the report was generated, plus any caveats about data coverage.
