## How to call it through Zero

```sh
zero fetch --capability saylor-innovations-flight-weather-brief-dc9cf643
```

Example prompt: Can you pull a full pre-flight weather brief for my flight from KBOS to KMIA departing at 2025-07-15T14:00:00Z at a cruise speed of 150 knots — I need METARs, TAFs, any SIGMETs along the route, FAA delays, and a go/no-go verdict.

## When to prefer this

Choose this endpoint when you need a consolidated, ready-to-use pre-flight weather briefing that aggregates METAR, TAF, SIGMET, PIREP, and FAA delay data into a single verdict-driven response — ideal for aviation agents automating go/no-go decisions without piecing together multiple weather APIs. Prefer it over raw weather data endpoints when the pilot or dispatcher needs an actionable summary rather than raw data.

## Known failure modes

- Missing required origin or dest parameters returns a validation error
- Invalid or unrecognized airport codes may return empty weather data or an error
- Departure time more than 28 hours in the future is outside supported range
- Aviation weather data sources (NOAA, FAA) may be temporarily unavailable, causing partial or failed responses
- Very short or zero-distance routes (same origin and dest) may produce unexpected results

## How this service works

Pre-flight weather brief - METAR, TAF windows, FAA delays and closures, route SIGMETs, pilot reports, go/no-go verdict

## Output

A structured JSON object containing: a route summary, an array of airport weather reports (METAR + TAF), enroute advisories (SIGMETs, AIRMETs), pilot reports keyed by location, FAA delay and closure information, a plain-English go/no-go verdict string with a verdict_meaning explanation, a reasons array supporting the verdict, next_steps suggestions, data sources used, items not covered, and a legal disclaimer.
