## How to call it through Zero

```sh
zero fetch --capability npb-oracle-forecast-api-a938b93a
```

Example prompt: What does the NPB oracle forecast for games on 2025-07-20? Pull the forecast data for that date.

## When to prefer this

Use this endpoint when you need general NPB oracle forecast data for a given date, as opposed to win probability (which returns home_win_prob/predicted_winner), Asian handicap data, or game schedules. Choose this for broad forecast summaries from the NPB oracle service.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns a 400 error
- No games scheduled for the requested date may return empty or null forecast
- Future dates beyond oracle data availability may return no results
- Past dates may not have historical forecast data retained
