## 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-mlb-slate-bundle-335e7418
```

Example prompt: Pull the full Fanfare MLB slate bundle for today, May 20, covering all games, GPP contest type — I want the projections, team stacks, lineup snapshot, and late-swap data all at once.

## When to prefer this

Use this endpoint when you need all MLB DFS data for a slate in a single call rather than hitting separate projection, lineup, and stack endpoints individually. It saves cost and latency by bundling slate context, player projections, team stacks, lineups, and late-swap data into one composite response. Prefer it for building DFS lineup tools, late-swap dashboards, or any workflow where you need the full picture of a day's MLB DFS slate at once.

## Known failure modes

- Missing required 'date' parameter returns a 400 validation error
- Invalid date format (not YYYY-MM-DD) returns a 400 error
- No games found for the specified date or filters returns an empty or 404 response
- Payment failure or insufficient USDC balance blocks access with a 402 response
- Invalid position or contest_type enum value returns a 400 error
- Requesting a future date with no confirmed lineups may return partial or placeholder data

## How this service works

Everything for the slate in one call: slate-context + per-player projections + team stacks + lineups snapshot + late-swap snapshot. Single composite payment. Params same as /projections.

## Output

A composite JSON object containing: slate-level context (games, venues, weather), per-player DFS projections, recommended team stacks, a current lineups snapshot, and a late-swap snapshot — all for the specified date and filters.
