Decode the composite verdict

Score a destination before you commit a send or a call. Fraud and trust-operations teams wire this endpoint into their pre-send gate; callers also run it ahead of a high-value voice dispatch. The endpoint is read-only and advisory — it sends nothing, routes nothing, and enforces nothing — so you decide how to act on the recommendation it returns. The composite score folds four detectors into one verdict. The live SMS-pumping / artificial-traffic check and (when you pass message_body) the outbound link-reputation scan run on the platform side; your own Verify Fraud Guard and Voice Biometrics scores pass in as verify_signal / voice_biometrics_signal and are folded into the same number. The composite is the worst present channel score, so a bad link or a flagged destination cannot be washed out by a clean aggregate. Band cutoffs reuse the SMS-pumping scorer’s thresholds, so a “high” verdict means the same thing whether the signal came from one channel or the fused whole.
Score bands decode as: 0–24 low, 25–54 elevated, 55–79 high, 80–100 critical. Bands map to actions as critical → block, high → review, and elevated | low → allow. No pass-through scores and no message_body returns a clean score: 0 / band: "low" — the empty ask never reads as a threat. The per-channel channels array tells you which detector drove the verdict, so the composite is never a black box.
