## 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 firearms-explosives-regulatory-compliance-brief-67a7059a
```

Example prompt: Give me a quick LLM-written compliance brief on the firearms and explosives regulations that have come out since January 1st — especially anything with upcoming deadlines.

## When to prefer this

Use this endpoint when you need a human-readable, deadline-aware narrative summary of firearms and explosives compliance obligations, rather than raw regulatory data. Ideal for compliance officers, legal teams, or agents that need to surface actionable rule changes without parsing raw regulatory feeds. Prefer this over general legal research tools when the domain is specifically firearms/explosives federal regulation.

## Known failure modes

- No regulatory changes in window — brief may indicate no material changes found
- Invalid 'since' date-time format returns a 400 validation error
- Payment not provided or insufficient — returns 402 Payment Required
- Service unavailability on Railway infrastructure returns 5xx errors
- LLM generation failure may fall back to template-based output

## How this service works

LLM-written compliance digest of the firearms & explosives rules in the window that actually matter (firearm, explosive, ammunition, ffl, silencer) — issuing agency named, deadlines called out.

## Output

Returns a JSON object containing a 'brief' field with a concise LLM-written narrative summarizing the most important firearms and explosives regulatory changes in the specified window, a 'generatedBy' field indicating whether an LLM or template produced it, and 'basedOnChanges' indicating how many underlying regulatory changes were considered.
