## 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 datakoot-federal-register-document-lookup-ec635102 -d '<json body>'
```

Example prompt: Can you pull up the details for Federal Register document 2024-24283 — I want to see the title, action type, abstract, and when it goes into effect.

## When to prefer this

Use this endpoint when you have a specific Federal Register document number and need structured metadata (title, action, abstract, dates, citation) for that exact document. Prefer this over search endpoints when the document number is already known. Use the search_documents or recent_documents sibling tools first if you only have keywords or a topic rather than a specific document number.

## Known failure modes

- Invalid or non-existent document number returns an error or empty result
- Document number formatted incorrectly (missing hyphens or wrong pattern) causes lookup failure
- Very recent documents may not yet be indexed and return no result
- Network or upstream Federal Register API outage causes timeout
