Bitcoin Up or Down 15-Minute Probability estimates p_up and p_down for quarter-hour windows using a broader caller-supplied trend sample. Send 8-240 ordered caller-supplied BTC 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 Solana. First-party, deterministic, memory-only execution with no input retention. It does not fetch exchange, oracle, or prediction-venue data; it never signs or places a trade. The probability is uncalibrated, venue resolution rules are not verified, and the output is not trading advice.
