Example prompt: What are the current USCG District 9 Local Notices to Mariners this week — any federal discrepancies, buoy issues, or waterway alerts on the Great Lakes?

## When to prefer this

Choose this endpoint when you need structured, machine-readable USCG District 9 Local Notices to Mariners data without manually parsing PDFs from NAVCEN. It is ideal for agents monitoring Great Lakes navigational safety, building maritime dashboards, or alerting users to aids-to-navigation discrepancies. Prefer this over scraping NAVCEN directly when you need reliable JSON output and a consistent schema.

## Known failure modes

- HTTP 402 returned if payment is not provided (unpaid route)
- Empty records array if no notices were issued for the current week
- Stale asOf date if the upstream NAVCEN source has not been updated
- Network timeout if the BNM Data Shop server is unavailable
- Malformed or missing PDF source links if NAVCEN changes its URL structure

## How this service works

Official public data as JSON. Unpaid paid routes return HTTP 402.

## Output

A JSON object containing: a boolean ok status, the product identifier ('uscg-d9-lnm'), the week (e.g. '35-2026'), the asOf date, the source URL pointing to NAVCEN, a status string, an array of notice objects (each with text, week, section, waterway, and sourceUrl), an array of record objects (each with id, url, date, firm/waterway, and type), and a recordCount integer.
