Check whether a phone number appears in criminal marketplace infrastructure or pivots to known scam wallets, kits, or actors via RelayShield's threat-intelligence corpus, and whether its SIM/eSIM was recently swapped (Twilio Lookup v2, cached 24h). Returns a high/medium/unknown verdict with timestamped evidence reasons. Call before your agent trusts an unknown caller or smishing sender.
