## 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-tsca-industrial-chemicals-compliance-digest-1b6188e1
```

Example prompt: Give me an LLM-written compliance digest of the TSCA industrial chemical rules that actually matter since January 1, 2025 — I want the key deadlines called out.

## When to prefer this

Use this endpoint when you need a concise, human-readable narrative summary of TSCA industrial chemical compliance obligations rather than raw Federal Register data. Ideal for compliance officers or AI agents that need a quick digest with deadlines called out, rather than a list of raw regulatory documents. Prefer this over raw rules endpoints when the consumer needs actionable prose rather than structured data.

## Known failure modes

- Invalid 'since' datetime format returns a 400 error
- No regulatory changes found in the window may return a sparse or minimal brief
- LLM generation failure may fall back to template-based output (generatedBy: 'template')
- Payment not completed returns 402 Payment Required
- Service unavailability returns 5xx errors

## How this service works

LLM-written compliance digest of the industrial chemicals under TSCA rules in the window that actually matter (tsca, chemical substance, significant new use, snur, toxic substances) — issuing agency named, deadlines called out.

## Output

Returns a JSON object with a 'brief' field containing an LLM-generated narrative summary of the most important TSCA industrial chemical regulatory changes in the window, a 'generatedBy' flag indicating whether it was LLM- or template-produced, and a 'basedOnChanges' integer showing how many underlying Federal Register changes were analyzed.
