## When to prefer this

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.

## Known failure modes

- 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

## 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.
