# Locus Seismic Design Property Scan

> Locus Seismic Design Property Scan is a paid API for AI agents from api.locus.report, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-16).

Runs a seismic design and property risk scan for a US address or ZIP code, returning local records, parcel rules, and risk signals that may affect property use, cost, or value.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-seismic-design-property-scan-98f16836 -d '<json body>'
```

Example prompt: Can you run a Locus property scan on 4521 Wilshire Blvd, Los Angeles, CA 90010 and tell me about any seismic risk signals, parcel rules, or local records that might affect how I could use or develop it?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.05) early-stage property intelligence scan covering seismic design parameters, local parcel rules, and risk signals for a US property — especially before commissioning full due diligence reports. Prefer this over general real estate APIs when seismic and local regulatory risk signals are specifically needed.

## Known failure modes

- Missing both address and ZIP — API requires at least one input field
- Invalid or non-US ZIP code format returns no results or an error
- Address not found in local records returns an empty records array
- Payment failure (x402 flow not completed) results in 402 response blocking access
- Ambiguous address string may return partial or mismatched parcel data

## How this service works

USGS seismic design parameters for an address. Perfect for: 'seismic design category for an address', 'Ss and S1 for a site', 'earthquake design values for a property', 'NEHRP seismic parameters', 'PGA for a location'. Returns USGS NEHRP-2020 design data at a US point: Ss, S1, PGA, SDS, SD1, site class, risk category, and seismic design category where USGS has finite values. Engineering hazard data, not a safety verdict. Charge-free when the address fails or USGS has no value.

## Output

Returns a JSON object with a scan ID, a timestamp, an array of property records (parcel rules, local regulations, risk signals), and any caveats about data completeness or recency.
