## 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 pipeline-hazmat-transport-compliance-digest-d428a2d2
```

Example prompt: Give me a plain-English compliance digest of the pipeline and hazmat transport rules from the Federal Register that have come out in the last 30 days, especially anything with upcoming deadlines.

## When to prefer this

Use this endpoint when you need a human-readable, LLM-synthesized summary of pipeline and hazmat transport compliance changes rather than raw rule data. Prefer this over the raw Federal Register rules endpoint when the user wants a narrative digest with deadlines called out, not a list of scored documents to parse manually.

## Known failure modes

- No relevant regulatory changes in the requested window — brief may be empty or minimal
- Invalid 'since' datetime format returns a validation error
- Payment not completed (x402 payment required) — returns 402 status
- LLM generation failure — may fall back to template-based generation
- Rate limiting or service unavailability on Railway hosting

## How this service works

LLM-written compliance digest of the pipelines & hazardous-materials transport rules in the window that actually matter (pipeline, hazardous material, hazmat, gas transmission, liquefied) — issuing agency named, deadlines called out.

## Output

A structured JSON object containing: a 'brief' field with an LLM-written plain-English summary of the most impactful pipeline and hazardous-materials transport regulatory changes; a 'generatedBy' field indicating whether it was LLM- or template-generated; and a 'basedOnChanges' integer showing how many Federal Register items were synthesized.
