# EPA TRI Chemical Releases by Facility

> EPA TRI Chemical Releases by Facility is a paid API for AI agents from fittings.sh, paid per call via x402, $0.01099/call, status unknown (last checked 2026-09-15).

Returns annual Toxics Release Inventory (TRI) chemical release data for a specific facility, totalled by chemical and broken down into air, water, land, and underground injection quantities in pounds.

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 epa-tri-chemical-releases-by-facility-7810c079
```

Example prompt: Pull the EPA TRI chemical release data for facility 77536DRPRK5900H for reporting year 2022 — I want to see the totals broken down by air, water, land, and underground injection for each chemical.

## When to prefer this

Use this endpoint when you need structured, per-chemical release totals for a specific TRI-reporting facility broken down by environmental medium (air, water, land, underground injection) for a given year. Prefer this over querying the EPA TRI database directly when you need a clean, pre-aggregated JSON response without parsing raw EPA query outputs. Best for compliance research, environmental due diligence, ESG analysis, journalism, or any agent workflow that needs machine-readable pollution data by facility.

## Known failure modes

- Invalid or unknown facility ID returns empty results or an error
- Year before 1987 (TRI program start) returns no data
- maxRows parameter out of range (must be 1–600) may cause validation error
- Facility did not file a TRI report for the requested year — empty result set
- Network timeout or upstream EPA data source unavailability

## How this service works

Chemical releases reported by one TRI facility for one reporting year, in pounds, totalled per chemical and split into air, water, land and underground injection.

## Output

A structured response listing each chemical released by the facility in the given year, with total pounds released disaggregated into four environmental media: air, water, land, and underground injection. May return multiple rows per chemical if the upstream TRI dataset contains multiple entries.
