How this service works
Official public data as JSON. Unpaid paid routes return HTTP 402.
Output
A JSON object containing: ok status, publication date (asOf), week identifier (e.g. '32-2026'), source URL pointing to NAVCEN, list of notices (each with text, week, section, waterway, and source PDF URL), product identifier ('uscg-d11-lnm'), structured records (each with id, url, date, firm/waterway, and type), and a total record count.
Example use cases
Pre-voyage hazard briefing
“Before I head out from the Bay Area, can you pull the latest USCG District 11 notices to mariners and tell me about any light outages or channel hazards I should know about?”
Weekly maritime alert monitoring
“Every Monday, fetch the new USCG District 11 Local Notices to Mariners and summarize any federal discrepancies or new navigation warnings posted that week.”
Waterway-specific safety check
“Are there any current USCG notices or aids-to-navigation discrepancies affecting the Berkeley Marina Channel right now, according to District 11 LNMs?”
Technical details
Endpoint
GEThttps://ticks.bnm.farm/mariners-d11When to prefer
Choose this endpoint when you need structured, machine-readable JSON of USCG District 11 Local Notices to Mariners without scraping NAVCEN PDFs yourself. It is ideal for maritime safety applications, voyage planning tools, or automated monitoring systems covering Pacific Coast / San Francisco Bay Area waterways. Prefer this over raw PDF parsing or manual NAVCEN checks when freshness (current week) and structured output are required.
Side effects
- HTTP 402 if payment header is missing or invalid — endpoint requires x402 micropayment of $0.05 USDC
- No notices returned if there are no discrepancies for the current week
- Source NAVCEN data may be temporarily unavailable, resulting in stale or empty response
- Malformed payment credentials may cause authentication failure before data is returned
