## 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-drinking-water-violations-scan-51cbc035 -d '<json body>'
```

Example prompt: Can you pull the Locus drinking water violation scan for 742 Evergreen Terrace, Springfield, IL 62704 — I want to see any water quality issues or compliance violations on record before we make an offer on the house?

## When to prefer this

Use this endpoint when you need to specifically check drinking water violation history for a US property or ZIP code, especially during real estate due diligence, environmental risk screening, or public health research. It is purpose-built for water compliance data, unlike general property scan endpoints on the same platform.

## Known failure modes

- Address not found or unresolvable — empty records array returned
- Invalid ZIP code format — validation error
- No violation records found for location — records array empty with caveats
- Payment failure via x402 — 402 response before data is returned
- Service unavailable or upstream data source error — 5xx response

## How this service works

EPA drinking-water violations for a water system / area. Perfect for: 'drinking water violations for an address', 'SDWIS violations near me', 'water quality violations for a county', 'has my water system had violations', 'EPA drinking water compliance lookup'. Returns EPA SDWIS health-based and monitoring violations with system, contaminant, and date context, plus ECHO fallbacks. A covered system with zero violations is the real EPA answer. Charge-free when sources are unavailable or it fails.

## Output

A JSON object containing a scan ID, list of drinking water violation records associated with the property or area, any relevant caveats about data coverage, and a timestamp indicating when the report was generated.
