## 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 us-facility-environmental-due-diligence-api-122ee3bc
```

Example prompt: Can you pull the full EPA environmental risk profile for Chemours' facility in Fayetteville, North Carolina — I need the compliance status, any enforcement actions or penalties, toxic releases, and the overall environmental risk score?

## When to prefer this

Use this endpoint when you need a fast, single-call environmental due-diligence verdict for a US facility, combining multiple EPA data sources (ECHO, TRI, GHGRP, FRS) into one scored, cited JSON. Prefer it over raw EPA APIs when you want a normalized risk score and don't want to aggregate multiple government endpoints yourself. Ideal for ESG screening, M&A due diligence, real estate assessment, or compliance monitoring workflows.

## Known failure modes

- Facility not found in EPA FRS registry — returns empty or no-match result
- Ambiguous name matches multiple facilities — may require state or coordinates to narrow
- Coordinates outside the US — endpoint only covers US facilities
- Registry ID does not exist in FRS — returns not-found error
- Rate limit or payment failure — HTTP 402 or 429 response

## How this service works

US facility environmental due-diligence: one cited JSON verdict fusing EPA compliance status, enforcement history, penalties, toxic releases and reported greenhouse gases, with a 0 to 100 environmental-risk score, for a company name, EPA FRS registry id, address, or coordinates.

## Output

A cited JSON object containing: an environmental risk score from 0 to 100, EPA compliance status, enforcement history, penalties assessed, toxic release inventory (TRI) data, reported greenhouse gas emissions, and source citations — all fused from EPA FRS, ECHO, TRI, and GHGRP databases.
