## How to call it through Zero

```sh
zero fetch --capability env-screen-a42d8906
```

Example prompt: Can you search the EPA facility registry for any regulated facilities named 'Chemours' in North Carolina — I need their EPA FRS IDs and compliance status as a first screening step?

## When to prefer this

Choose this endpoint when you need a fast, inexpensive first pass to identify EPA-regulated facilities by name or geography before committing to a more detailed (and expensive) full environmental compliance verdict. It is ideal for due diligence pipelines, site screening, regulatory research, or any workflow where you need to resolve a facility to its EPA FRS ID before deeper analysis.

## Known failure modes

- No facilities found matching the name or location — returns empty candidate list
- Ambiguous name matches too many facilities — results may require further filtering by state or NAICS
- Invalid latitude/longitude range — request rejected with validation error
- Radius exceeds 25-mile maximum — request rejected
- Address geocoding fails for malformed or non-US address — no results returned
- Missing both name and location inputs — request rejected as insufficient search criteria

## How this service works

Screen US EPA-regulated facilities: fuzzy name or location search returning ranked candidate facilities with their EPA FRS registry id and compliance status — the cheap first step before a full env facility verdict.

## Output

A ranked list of candidate EPA-regulated facilities matching the search criteria, each including the EPA FRS registry ID, facility name, location details, and current compliance status — suitable for triaging before a more detailed environmental verdict lookup.
