      summary: Verdict
      description: 'One-call bet verdict: fair price vs the market + a plain-English call. 5 credits.


        Give it a specific bet and it returns the no-vig fair price, how the best

        available (and your) price compares as EV, which book has the best number,

        and a verdict: BET / LEAN / FAIR / PASS (or NO_DATA). Reuses the same sharp

        no-vig math as /ev and /consensus.


        Examples:

        /v1/verdict?sport=baseball_mlb&team=Yankees&market=h2h&side=Yankees&book=draftkings
