## How to call it through Zero

```sh
zero fetch --capability climatepulse-event-weather-brief-cfb94825
```

Example prompt: Can you pull a full weather brief for my outdoor wedding at Napa Valley, California on June 14, 2025 — I need rain odds, heat risk, a go/no-go timeline, and a heat-safety plan for 200 guests?

## When to prefer this

Use this endpoint when planning or advising on any outdoor event (wedding, marathon, festival, corporate event) and a comprehensive risk assessment is needed — including historical climate odds, live forecast integration, actionable go/no-go timelines, and safety plans. Prefer over generic weather APIs when event-specific guidance, contingency planning, and heat-safety recommendations are required.

## Known failure modes

- Date too far in the future for any forecast data — historical odds still returned but no live forecast
- Invalid or unrecognizable location — API returns location parsing error
- Missing required parameters (date or location) — returns 400-level error
- Location outside NASA POWER data coverage — reduced historical accuracy
- Network timeout fetching live MET Norway forecast — brief generated from historical data only

## How this service works

Premium event-weather brief for any date and location worldwide. Rain, heat, frost, wind, and extreme-heat odds computed in code from 10 years of actual NASA POWER reanalysis rows (counted, not model-estimated), the live 10-day MET Norway forecast when the date is in range, a dated go/no-go decision timeline, contingency plan, schedule guidance, and heat-safety plan for weddings, festivals, marathons, and any outdoor event.

## Output

A structured event weather brief containing: historical climate odds (rain, heat, frost, wind, extreme heat) computed from 10 years of NASA POWER reanalysis data; live MET Norway 10-day forecast if the date is within range; a dated go/no-go decision timeline; a contingency plan; schedule guidance; and a heat-safety plan tailored to the event type (wedding, marathon, festival, etc.)
