How this service works
Official public data as JSON. Unpaid paid routes return HTTP 402.
Output
A JSON object containing a boolean success flag, product identifier ('uscg-d17-lnm'), current week label (e.g. '35-2026'), asOf date, source URL pointing to the NAVCEN website, 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 Alaska navigation briefing
“What are the current USCG District 17 navigation notices for this week? I need to know about any buoy outages or light discrepancies in Alaskan waters before we depart.”

“Check the latest Local Notices to Mariners for District 17 and flag any discrepancies or alerts specifically around Adak Island or the Aleutian chain.”
Aggregating marine safety data for a dashboard
“Fetch this week's structured USCG D17 LNM records so I can log the notice IDs, waterway names, and source PDF URLs into our maritime safety tracker.”
Technical details
Endpoint
GEThttps://ticks.bnm.farm/mariners-d17?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable USCG District 17 (Alaska) Local Notices to Mariners data without scraping PDFs from NAVCEN yourself. It is ideal for maritime safety dashboards, voyage planning tools, or automated monitoring of Alaskan waterway aid-to-navigation discrepancies. Prefer this over raw NAVCEN PDF access when you need JSON output, a consistent schema, and programmatic access with per-call micropayment pricing.
Side effects
- HTTP 402 if payment is not provided or the x402 payment header is missing/invalid
- Empty records array if no notices were published for the current week
- Source NAVCEN website unavailable causing stale or failed data fetch
- Malformed or missing PDF at the source URL resulting in parsing errors
