Ethereum Up or Down 5-Minute Probability estimates p_up and p_down for rapid near-close wi
Ethereum Up or Down 5-Minute Probability estimates p_up and p_down for rapid near-close windows where the freshest supplied observations matter most. Send 8-240 ordered caller-supplied ETH price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or So…
