What it does

Single-file Python scanner that reads Polymarket's public APIs, finds mutually exclusive (negRisk) events where buying every YES or every NO costs less than the fixed payout, and walks real order-book depth to size each gap. A paper mode buys opportunities with a fake bankroll, settles them from final prices and compares the result with a savings account. Never places orders or needs a wallet.
