How this service works
Official public data as JSON. Unpaid paid routes return HTTP 402.
Output
A JSON object with ok status, current date (asOf), ISO week identifier (week), overall status, and an array of notices each containing the notice text, week, section category (e.g. Federal Discrepancies), waterway name, and a direct URL to the source USCG PDF publication.
Example use cases
Pre-voyage navigation safety check
“Before I head out on my boat this weekend, can you check the latest USCG District 13 local notice to mariners and flag any missing lights, damaged buoys, or waterway hazards I should know about?”
Anacortes Harbor transit planning
“I'm transiting through Anacortes Harbor next week — can you pull the current LNM notices for District 13 and tell me if any aids to navigation in that area are out of service or have reported discrepancies?”
Weekly maritime hazard monitoring
“Give me a summary of this week's USCG District 13 notices to mariners, including any federal discrepancies affecting Washington or Oregon waterways, and link me to the source PDF.”
Technical details
Endpoint
GEThttps://ticks.bnm.farm/mariners?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable USCG District 13 LNM data without parsing raw PDFs from navcen.uscg.gov. Ideal for maritime trip planning, vessel routing agents, or automated safety monitoring for Pacific Northwest waterways. Prefer over manual PDF scraping when you need JSON-formatted notices with waterway metadata already extracted.
Side effects
- Upstream USCG data unavailable: may return stale asOf date or empty notices array
- Payment not included or insufficient: 402 Payment Required response blocking access
- USCG publishes LNMs weekly so data may lag by up to a week from real-world events
- Network timeout if navcen.uscg.gov source is slow to respond
- No notices for a given week if USCG has not yet published that edition
