## 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 fanfare-run-mlb-lineups-f1734782
```

Example prompt: Pull up the confirmed batting orders and probable pitchers for all MLB games on June 15, 2025 — I need to check for any late scratches before I lock my fantasy lineup.

## When to prefer this

Use this endpoint when you need confirmed, real-time MLB lineup data including batting order positions, probable pitchers, and late scratches for fantasy sports decisions. Prefer this over generic sports APIs when you specifically need DFS-ready lineup confirmation with scratch intelligence for a particular date or game.

## Known failure modes

- Missing required 'date' parameter returns a 400 validation error
- Lineups not yet released for a future game may return empty or partial data
- Invalid team_id or game_pk returns empty results or 404
- Date format not matching YYYY-MM-DD causes a parsing error
- Service may have delays if upstream MLB Stats API is slow or unavailable

## How this service works

Confirmed batting orders + probable pitchers + late scratches per MLB game for a date. The single biggest fantasy lever. Params: date (YYYY-MM-DD), team_id, game_pk.

## Output

A structured response per MLB game containing confirmed batting orders, probable starting pitchers, and any late scratches, filtered optionally by team_id or game_pk for the requested date.
