## 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-regulations-pipeline-federal-register-public-inspection-fb02fdbe
```

Example prompt: Can you pull tomorrow's Federal Register public inspection queue and show me all the rules and notices that are scheduled to publish — especially anything from the EPA or FDA?

## When to prefer this

Use this endpoint when you need advance visibility into federal regulatory documents before they are officially published in the Federal Register. It is ideal for compliance monitoring, policy tracking, and regulatory intelligence workflows that need to act on upcoming rules or notices as early as possible. Prefer this over the US Regulation Search or US Regulation Updates endpoints when you want documents that are in the pipeline but not yet published.

## Known failure modes

- No documents returned if the queue is empty or no documents match the type/agency filters — a 'note' field is present in this case
- Invalid agency slug returns empty results rather than an error
- Exceeding 5 agency slugs in the comma-separated filter may be silently truncated
- Data reflects the live public inspection queue and may change rapidly as documents are added or released
- Fields are normalized (not official record) — 'modified: true' is always set as a caveat

## How this service works

US federal regulations in the pipeline — documents on public inspection at the Federal Register, filed by agencies and scheduled to publish, with type, agencies, filing time and the scheduled date. Use to see tomorrow's rules, notices and executive orders before they are published.

## Output

Returns a list of federal regulatory documents currently in the public inspection queue at the Federal Register. Each document includes its title, type (rule, proposed_rule, notice, or presidential), filing agencies, agency slugs, docket numbers, the time it was filed, filing type, scheduled publication date, page count, and links to the HTML and PDF versions. The response also includes the total count of documents on inspection before filtering, retrieval timestamp, and a source citation.
