## 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-environmental-history-lookup-59974e9c -d '<json body>'
```

Example prompt: Can you run a Locus property scan on 742 Evergreen Terrace, Springfield, IL 62704 and tell me about any environmental risks, parcel rules, or local record flags that might affect its value or use?

## When to prefer this

Use this endpoint when you need a fast, low-cost early-stage property intelligence scan for a US address, particularly before deeper due diligence. Ideal for flagging environmental history, zoning constraints, and risk signals without committing to a full property report. Prefer this over general web search when you need structured parcel-level data.

## Known failure modes

- Address not found or unresolvable — empty records array returned
- ZIP code resolves to no parcels — minimal or empty response
- Malformed address string — API may return no results without a clear error
- Network or server error — HTTP 5xx with no data
- Payment failure — HTTP 402 if x402 payment not processed correctly

## How this service works

Address-level environmental record proximity. Perfect for: 'environmental hazards near an address', 'EPA TRI / RCRA sites near a property', 'is there a polluter nearby', 'radon zone for an address', 'environmental due diligence for a property'. Returns proximity-ranked EPA Toxics Release Inventory + RCRA facilities, nearest large-quantity generator, and the county radon/background composite. National. Not a contamination or safe/unsafe verdict.

## Output

Returns a JSON object with a report ID, a timestamp, an array of property records (zoning, parcel, environmental, and risk signals), and caveats about data completeness or freshness.
