of legs with American prices, returns the independent-baseline
parlay price (product of marginal implied probs converted back to

This is *not* a real SGP price — real SGP prices include
correlation modeling (correlated outcomes from the same game push
the parlay price away from the independent product in either
direction). Use the full /v1/sgp/price for literature-based
correlation-adjusted pricing.

description: '**Free no-auth positive-EV demo.** Surfaces the top moneyline
positive-EV opportunities for a popular US sport, no API key

How edge is computed: Pinnacle (sharp book) two-sided ML price is
devigged to a no-vig fair probability per side. For every other
book''s offered price on the same side, edge = fair_prob -
book_implied_prob. Anything above 0 is a "+EV" play vs Pinnacle as
anchor.
