# SiteCheck Trade & Energy – EPA GHGRP Facility Emissions by Year

> SiteCheck Trade & Energy – EPA GHGRP Facility Emissions by Year is a paid API for AI agents from api.tradeenergy-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns EPA Greenhouse Gas Reporting Program (GHGRP) CO2e emissions by year for a single facility, identified by its GHGRP facility ID.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sitecheck-trade-energy-epa-ghgrp-facility-emissions-by-year-6f336f46
```

Example prompt: Can you pull up the EPA GHGRP reported greenhouse gas emissions by year for facility 1000001? I want to see the annual CO2e figures in metric tons as reported to the EPA.

## When to prefer this

Use this endpoint when you need official EPA GHGRP emissions data (CO2e summed across all gases) for a specific, known facility identified by its GHGRP facility ID. Prefer this over manual EPA Envirofacts queries for automated/agent workflows. It does not support facility search by name or sector-level aggregation — you must already know the GHGRP facility ID.

## Known failure modes

- Invalid or non-existent facility ID returns empty results or an error
- Facility ID not yet in GHGRP system returns no data
- EPA Envirofacts upstream API outage causes failure or stale data
- Non-numeric characters in facility ID rejected by schema validation
- Facility with no reported years returns empty years array

## How this service works

EPA Greenhouse Gas Reporting Program (GHGRP) reported emissions for one facility by year, from EPA Envirofacts (CO2e summed across gases per year, as published). Uses the GHGRP facility id (e.g. 1000001). Facility search and sector breakdowns are not included.

## Output

A JSON object containing an array of year/CO2e metric-ton pairs representing each year the facility reported to the EPA GHGRP, along with the source EPA Envirofacts URL, total row count, the GHGRP facility ID, and a timestamp of when the data was checked.
