## 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 space-weather-alerts-watches-warnings-noaa-fd3f960f
```

Example prompt: Check NOAA's space weather alerts from the last 48 hours and tell me how many warnings, watches, and alerts have been issued and what the latest headlines say.

## When to prefer this

Use this endpoint when you need a quick structured count and summary of recent NOAA space weather alerts, watches, and warnings — particularly when you want to triage whether any active advisories exist without parsing raw NOAA RSS feeds. It is ideal for monitoring dashboards, automated briefing agents, or pre-operation checks for HF radio, satellite, or power grid applications. Prefer it over raw NOAA feeds when you need clean, typed, machine-readable output with headline extraction already done.

## Known failure modes

- Invalid hours parameter (outside 1–72 range) may return an error or default to 24 hours
- Upstream NOAA data unavailable may result in a degraded response with partial or empty data
- No alerts in the requested window returns count of 0 and empty byType/latest fields
- Network timeouts from upstream NOAA sources may delay or fail the response

## How this service works

Space weather alerts, watches and warnings NOAA issued in the last 1-72 hours, counted by type with headlines.

## Output

Returns a JSON object with: total alert count for the window, counts broken down by type (ALERT, WATCH, WARNING, SUMMARY, OTHER), an array of the latest alerts with their type, issued timestamp, and headline, a summary and verdict string, the data source and source URL, the lookback window in hours, and optional degraded/disclaimer fields if the data source had issues.
