Checks 1–7

Flip is the execution layer for prediction markets. Buy a single Polymarket or Kalshi outcome, or combine up to 6 into one leveraged parlay — funded by one x402 USDT payment on X Layer. Quotes are free; placing charges stake ($1–$50) plus a 1% fee (min $0.10), with the exact amount returned in the 402 at request time. Deterministic, published pricing with a correlation guard and hard caps. Endpoints: GET /markets, POST /quote, POST /nl/quote, POST /place (x402), GET /position/:id.
