## 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 railroad-safety-operations-compliance-brief-aab7ff29
```

Example prompt: Give me a compliance brief on the most important railroad safety and operations rules that came out since January 1, 2025, and flag any upcoming deadlines I need to act on.

## When to prefer this

Use this endpoint when you need a concise, human-readable executive summary of railroad safety and operations compliance obligations rather than a raw list of rule changes. Ideal for compliance officers, legal teams, or AI agents that need to surface only the most actionable regulatory developments with deadlines, without processing raw Federal Register entries. Prefer this over the raw rules endpoint when brevity and prioritization matter more than exhaustive detail.

## Known failure modes

- Invalid or future 'since' date returns an error or empty brief
- No regulatory changes in the window returns a brief with basedOnChanges: 0
- LLM generation failure may fall back to template-generated brief
- Payment not included or incorrect results in HTTP 402 response
- Malformed date-time format for 'since' parameter returns validation error

## How this service works

LLM-written compliance digest of the railroad safety & operations rules in the window that actually matter (railroad, rail, locomotive, train control, track safety) — issuing agency named, deadlines called out.

## Output

A plain-language LLM-written brief summarizing the handful of railroad safety and operations regulatory changes that matter most within the requested window, with deadlines called out. Also returns whether it was generated by LLM or template, and how many underlying Federal Register changes it was based on.
