## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability uscg-district-13-local-notice-to-mariners-lnm-feed-3e829110
```

Example prompt: Pull the current USCG District 13 Local Notice to Mariners and tell me if there are any active aids-to-navigation discrepancies or hazards reported for this week in the Pacific Northwest.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
