## 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-8-local-notices-to-mariners-bnm-data-shop-1a752e1b
```

Example prompt: Pull the latest USCG District 8 Local Notices to Mariners so I can see any current navigational discrepancies or destroyed aids affecting waterways in that region this week.

## When to prefer this

Use this endpoint when you need machine-readable, structured access to USCG District 8 Local Notices to Mariners without scraping NAVCEN PDFs yourself. Ideal for maritime safety applications, vessel routing agents, fleet monitoring systems, or any workflow that needs weekly Gulf Coast navigational discrepancy data delivered as clean JSON at low cost per call.

## Known failure modes

- HTTP 402 if payment is not attached or insufficient — endpoint requires $0.05 USDC per call
- Empty notices array if no discrepancies were published for the current week
- Source data unavailability if NAVCEN has not yet published the current week's LNM PDF
- Network timeout if the upstream NAVCEN site is slow or unavailable

## How this service works

Official public data as JSON. Unpaid paid routes return HTTP 402.

## Output

A JSON object containing the current week identifier, publication date, source URL, and an array of notices — each with the notice text, waterway name, section type (e.g. Federal Discrepancies), and a link to the source PDF. Also includes normalized records with unique IDs, dates, and record type for downstream processing.
