Costs ~$1.15 USDC (live, refreshed every 60s) per flip (0.0005 ETH game entry + gas + margin); read the live USDC figure from /preview.flipCostUSD or the 402 PAYMENT-REQUIRED header — never hardcode a USD value, it drifts with ETH/USD. Winnings paid from ETH pot. Returns heads/tails + current streak. The 2-hour pot awards 80% to longest streaks on the wall-clock UTC even-hour cliff. The jackpot requires hitting a target streak set by the contract (read live from /preview or /game-info — never hardcode it). HOW TO ACTUALLY PAY: see /integration for working code in 3 paths (MCP one-tool-call, @x402/fetch v2.4 SDK, hand-rolled curl). Test your payment client end-to-end without USDC at POST /flip/dry-run (free, same response shape). Accepts USDC on Base + Solana.
