## 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 us-federal-rulemaking-proposed-rules-search-719c271c
```

Example prompt: Find me the latest proposed rules from the EPA related to air quality standards — pull up to 10 documents including their comment periods and public comment counts, and filter to just Proposed Rule document types.

## When to prefer this

Use this endpoint when you need structured, normalized access to US federal proposed rules and rulemaking dockets without scraping Regulations.gov or the Federal Register manually. Ideal when filtering by agency, searching by keyword, or looking up a specific docket ID to get comment period and public participation data in a single call.

## Known failure modes

- Invalid docketId format returns no results or an error
- Unknown agency ID returns empty results
- Keyword with no matches returns an empty document list
- Limit out of range (>25 or <1) causes a validation error
- Network or upstream Regulations.gov API downtime returns a service error

## How this service works

Find US proposed rules and rulemaking dockets by docket id, keyword or agency: documents, comment period, public-comment count and Federal Register links. Source: Regulations.gov + Federal Register, public-domain.

## Output

Returns a list of rulemaking documents matching the query, including docket metadata, document type, comment period dates, public comment counts, and links to the Federal Register entries — normalized from Regulations.gov and Federal Register sources.
