## 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 nws-area-forecast-discussion-by-office-5af00d94
```

Example prompt: Pull up the NWS Area Forecast Discussion for the New York forecast office (OKX) — I want to see the meteorologists' reasoning, key messages, and long-term outlook sections.

## When to prefer this

Use this endpoint when you need the full meteorologist-authored narrative behind a regional forecast — including forecaster reasoning, key messages, aviation and marine sub-sections — rather than just structured forecast data (temperatures, precipitation probabilities). It is ideal for agents that need to explain *why* weather is expected to behave a certain way, or that serve aviation, marine, or emergency management audiences who rely on the AFD for professional situational awareness.

## Known failure modes

- Invalid or unrecognized office code returns an error or empty result
- NWS API outage or data unavailability causes upstream failure
- Office code provided in wrong format (e.g. lowercase or 4 letters) may fail validation
- Newly created or discontinued forecast offices may not have current data
- Rate limiting or payment failure at the x402 layer returns 402 Payment Required
