## How to call it through Zero

```sh
zero fetch --capability us-legislative-rulemaking-search-eba29281
```

Example prompt: Can you find proposed rules from the EPA about air quality standards — I want to see the latest rulemaking documents, how many public comments they've received, and links to the Federal Register entries?

## When to prefer this

Use this endpoint when you need to look up or search US federal rulemaking activity, including proposed rules, final rules, and notices from specific agencies. It is ideal for compliance research, policy monitoring, public comment tracking, or any task requiring structured access to Regulations.gov and Federal Register data without needing to scrape those sites directly.

## Known failure modes

- Invalid or non-existent docket ID returns empty results or an error
- Unknown agency ID filter returns no results
- Overly broad keyword returns up to the limit but may miss relevant documents
- API rate limiting or upstream Regulations.gov unavailability may cause timeouts
- No documents matching the specified documentType enum value returns an empty list
