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.
Example use cases
Weekly Great Lakes navigation hazard check
“Pull the latest USCG District 9 local notices to mariners and tell me if there are any active federal discrepancies or aids-to-navigation outages on the Great Lakes this week.”
Buoy outage alert for a specific waterway
“Are there any notices about lighted buoys or navigational aids being off-station or malfunctioning in the Alpena waterway area right now?”
Automated maritime safety monitoring
“Check the current USCG District 9 LNM feed and alert me if any new navigational discrepancies have been posted since last week, including which waterways are affected and the source PDF links.”
Technical details
Endpoint
GEThttps://ticks.bnm.farm/mariners-d9?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
