## 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 saylor-innovations-environmental-superfund-site-lookup-bbbdcd8b
```

Example prompt: Are there any EPA Superfund sites near coordinates 40.7128° N, 74.0060° W? I want to know the site names, how far away they are, their current cleanup status, and any hazard scores.

## When to prefer this

Use this endpoint when you need geospatial proximity lookups against the EPA National Priorities List — specifically when the user provides coordinates or an address that can be geocoded to lat/lon and wants to know about nearby Superfund contamination sites, their regulatory status, or environmental risk. Prefer this over general environmental data APIs when NPL-specific detail (EPA ID, listed/cleanup dates, hazard score) is required.

## Known failure modes

- Missing required lat or lon query parameters returns an error
- Non-numeric or out-of-range coordinate values may return an error or empty result
- No Superfund sites found near the coordinates returns found=false with an empty sites array
- Payment not included or invalid x402 payment header returns 402 Payment Required
- EPA data may have latency in reflecting the most recent NPL updates

## How this service works

Superfund sites near an address or coordinates (EPA NPL) - status, distance, hazard score and cleanup dates

## Output

A JSON object containing a boolean `found` flag, the queried coordinates, a count of matching sites, and an array of Superfund site records. Each site includes the site name, EPA ID, city, state, county, current status, distance in kilometers, date listed on the NPL, proposed listing date, deletion/partial deletion dates, hazard profile URL, and the site's own latitude/longitude.
