## 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 npb-box-score-api-full-post-game-box-score-by-date-fe2ad3ec -d '<json body>'
```

Example prompt: Can you pull up the full NPB box score for all games on July 3, 2025, including the batting lineups, inning-by-inning scores, pitchers who appeared, home runs hit, and attendance figures?

## When to prefer this

Use this endpoint when you need comprehensive post-game box score data for NPB games — specifically when you need batting lineups in actual played order, inning-by-inning scoring breakdowns, pitcher usage sequences, home run logs, attendance, and umpire info all in one call. Prefer this over the basic results endpoint when doing detailed post-game analytics, fantasy baseball lineup updates, pitcher tracking, or building AI baseball analytics pipelines that require structured full-game summaries.

## Known failure modes

- Date not in YYYY-MM-DD JST format returns a 400 or empty result
- No games scheduled on the given date returns an empty games array
- Future or same-day dates may return incomplete or no post-game data since records are only available after games conclude
- Payment failure (insufficient USDC balance on Solana mainnet) blocks the call
- Rate limiting or upstream npb.jp unavailability may cause 5xx errors
