## 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 phoenix-event-window-rain-probability-forecast-98a2f279
```

Example prompt: What's the rain probability and overall weather verdict in Phoenix tomorrow from 3pm to 8pm? I'm trying to decide if our outdoor fundraiser should go ahead.

## When to prefer this

Use this endpoint when you need a concise, event-window-scoped weather risk summary specifically for Phoenix, AZ, without having to supply coordinates. It is preferable to a generic forecast API when you want a single verdict and rain probability over a defined time window rather than hourly data, and when your scheduling logic needs comfort_index and severity_flags for go/no-go decisions.

## Known failure modes

- Invalid ISO-8601 datetime format for start or end returns a validation error
- End time more than 12 hours after start time is rejected
- Window start time too far in the future may return low-confidence or unavailable forecast
- Missing required authentication or x402 payment header results in 402 Payment Required
- Network timeout or upstream weather model unavailability returns a 5xx error

## How this service works

Will it rain in Phoenix during your event window — Event-window weather odds for Phoenix: pass a start and end time (or omit them for the next six hours) and get rain probability and expected conditions across the window — built for scheduling decisions. Same shape as /v1/forecast/window with the Phoenix coordinates built in.

## Output

A JSON object containing: rain_probability (0–1), expected_precip_mm, temp_range with low and high values, wind_max, comfort_index (0–1), severity_flags (array of warning strings), and a verdict string summarizing overall conditions for the requested Phoenix time window. Also includes metadata about the window and model.
