Example prompt: Can you get me a cryptographically verified outcome for the NFL game between the Kansas City Chiefs (home) and the Buffalo Bills (away) on 2024-01-21? I need a signed settlement receipt I can use on-chain.

## When to prefer this

Choose this endpoint when you need a cryptographically attested, independently verifiable game outcome suitable for smart contract settlement, on-chain dispute resolution, or compliance-grade sports verification. It is uniquely suited over generic sports APIs when the consumer requires a signed receipt on Base rather than a plain data response. Supports NFL, NBA, MLB, NHL, EPL, MLS, NCAAF, NCAAB, and major esports titles.

## Known failure modes

- Game not yet completed — score not available
- Teams or game date not found across any provider source

- Invalid sport enum value provided
- game_date format incorrect (must be YYYY-MM-DD)
- home_team or away_team name not recognized
- Payment not processed — x402 payment required at $0.50 USDC per call
