## 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-1-local-notices-to-mariners-7a9b8b96
```

Example prompt: Pull the latest USCG District 1 Local Notices to Mariners and show me any current aid-to-navigation discrepancies or waterway advisories, like buoy outages or channel issues.

## When to prefer this

Use this endpoint when you need machine-readable, structured JSON of USCG District 1 Local Notices to Mariners rather than parsing raw PDFs from NAVCEN directly. Ideal for automated pre-voyage checks, chart update workflows, or maritime safety monitoring agents operating in the New York/District 1 area. Prefer this over scraping NAVCEN PDFs manually when you need reliable, parsed notice records on demand.

## Known failure modes

- HTTP 402 if payment is not included — endpoint requires $0.05 USDC per call via x402 protocol
- Empty records array if no discrepancies were issued for the current week
- Stale asOf date if upstream NAVCEN data has not been refreshed
- Network timeout if upstream NAVCEN source is unavailable
- Malformed or missing PDF source if NAVCEN changes their URL structure

## How this service works

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

## Output

Returns a JSON object with fields: ok (boolean), product identifier ('uscg-d1-lnm'), status, asOf date, week label (e.g. '35-2026'), source URL pointing to NAVCEN, recordCount (integer), records array (each with id, url, date, firm/waterway, type), and notices array (each with text description, week, section, waterway, and sourceUrl to the PDF). Unpaid requests return HTTP 402.
