X402 · Coherence Gate
Use for: scoring whether your own independent signal paths agree before you act — submit each path's vote on your proposed action (direction for/against/flat, confidence = weight) and your own threshold; the gate computes coherence = |Σ w·d| / Σ w (the ScriptMasterLabs Coherence Gate formula, 402Gate spec v0.1 §3, weight = confidence only) and returns the reading plus a pass/void verdict. Pass requires a for-side consensus, coherence at or above your threshold, and at least 2 independent source families among voting paths (family = source label prefix before ":"); a coherent against consensus is a void, never a pass; single-family or no-vote submissions are refused uncharged. Source labels are caller-supplied and unverified (independence_assurance: source_labels_only_not_verified). Don't use when: you need SML's own signals (this endpoint fetches none and adds no vote), a payee pre-payment check (use /x402/spend-gate), or a trade execution (no funds move). A separate instance from the Arc Coherent Gate and the PRO-LO coherence feed — no reading crosses surfaces. Pay 0.1 USDC on Base using the fresh PAYMENT-REQUIRED challenge and caller-authorized PAYMENT-SIGNATURE.
