## 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 mlb-win-probability-oracle-14e200a5
```

Example prompt: What are the MLB win probabilities for all games on June 15, 2025 — I want to see the predicted winners and how confident the oracle is for each matchup?

## When to prefer this

Use this endpoint when you need MLB-specific win probability and predicted winner data with confidence scores for a given calendar date. Prefer this over generic sports APIs when you need structured probabilistic predictions (home_win_prob as a 0-1 value) rather than just odds or box scores. Particularly useful for sports betting analysis, fantasy baseball, or game preview automation on Solana-based x402 payment workflows.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) — returns 400 Bad Request
- No MLB games scheduled on the given date — returns empty list or 404
- Future date beyond available forecast window — may return empty or error
- Payment not provided or invalid — returns 402 Payment Required
- Service downtime on Railway deployment — returns 503

## How this service works

MLB (Major League Baseball) win probability for the given date. Returns predicted home_win_prob, predicted_winner, confidence per game (Solana mainnet).

## Output

Returns a list of MLB games for the requested date, each with a home_win_prob value (0-1 float), a predicted_winner (team name), and a confidence score indicating how certain the prediction is.
