## 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 policypulse-federal-register-search-0d524c9f
```

Example prompt: Search the Federal Register for any new SEC rules or proposed rules on stablecoins — I need the effective dates, comment deadlines, and docket IDs. Also check if any of those comment periods are still open.

## When to prefer this

Use this endpoint when you need authoritative, deterministic, structured data directly from the US Federal Register — not an AI summary or interpretation. Ideal when you need exact effective dates, comment deadlines, or docket IDs for compliance purposes. Prefer this over general web search when you need official regulatory documents with metadata. Use mode=open-comments when you specifically want to find active public comment periods closing soon.

## Known failure modes

- No matching documents found for query — returns empty results
- Overly broad query returns too many documents — agent should narrow the search term
- Payment not included or invalid — returns 402 Payment Required
- Federal Register API upstream outage — returns 503 or timeout
- Invalid mode parameter — returns 400 Bad Request

## How this service works

Federal Register search, deterministic. Answers "new SEC rules on stablecoins", "is there an open comment period on AI", "when does this rule take effect". Full-text search over every US federal rule, proposed rule and notice, with effective dates, comment deadlines and docket ids — or mode=open-comments for comment periods closing soonest. Typed documents straight off the official API. No LLM, no key, public domain.

## Output

Returns a list of matching Federal Register documents (rules, proposed rules, or notices) including document titles, agency names, effective dates, comment deadlines, and docket IDs. When mode=open-comments is used, returns documents with open comment periods sorted by soonest-closing deadline. Data is typed and sourced directly from the official Federal Register API with no LLM interpretation.
