Know Your Merchant (KYM) trust score: pass a merchant domain and get a deterministic 0-100 trust score with a band (high/medium/low/very_low/avoid) and human-readable reasons. Live signals: domain age from the RDAP registry of record, malware/phishing blocklist verdict via Cloudflare Security DNS, TLS certificate health, mail capability, and refund/privacy/contact page presence. The merchant-side check an agent runs BEFORE committing funds — the complement to know-your-agent.
