## 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 epa-tri-facilities-lookup-by-zip-or-city-5bf79e64
```

Example prompt: Find all the industrial facilities in ZIP code 77002 that report to the EPA Toxics Release Inventory — I need their TRI facility IDs to look up their chemical release quantities.

## When to prefer this

Use this endpoint when you need to identify EPA Toxics Release Inventory (TRI) reporting facilities within a US geographic area (by ZIP code or city/state) as a first step before querying chemical release quantities. Prefer this over general business or facility search APIs when environmental compliance, toxic chemical reporting, or EPA regulatory context is specifically required.

## Known failure modes

- Missing required location parameter (neither zip nor city+state provided) — returns a validation error
- Invalid ZIP code format or unrecognized city/state combination — returns empty results or error
- Limit parameter out of range (below 1 or above 50) — returns a validation error
- No TRI-reporting facilities found in the specified area — returns an empty list
- Upstream EPA data temporarily unavailable — returns a service error

## How this service works

Industrial facilities reporting to the EPA Toxics Release Inventory in a ZIP code or a city, with the TRI facility id needed to pull their release quantities.

## Output

A list of industrial facilities (up to the specified limit, default 20) in the queried ZIP code or city/state that report to the EPA Toxics Release Inventory. Each record includes the TRI facility ID, facility name, and location details needed to subsequently query chemical release quantities.
