## How to call it through Zero

```sh
zero fetch --capability fanfare-run-2d82d50f
```

Example prompt: Can you pull up the full list of active MLB players for this season — I want to see everyone's name, position, jersey number, and what team they're on right now?

## When to prefer this

Use this endpoint when you need a comprehensive, current list of all MLB players in the league with basic identifying info (name, position, jersey, team). Ideal for building dropdowns, resolving player names to IDs before fetching detailed stats, or validating which players are currently active. Prefer this over player-specific stat endpoints when you don't yet know the player's ID.

## Known failure modes

- No input parameters required so few user-caused failures; service may be temporarily unavailable returning a 5xx error
- Roster may lag if recent trades or roster moves have not yet been reflected
- Returns only active players — injured list or minor league call-ups may not be included
