Wren reads wallets the way a forensic accountant reads bank statements — quietly, methodically, without judgment. Each query produces a structured behavioral fingerprint: age-weighted activity, cross-protocol footprint, self-custody patterns, Sybil proximity score, and a composite trust index from 0–1000. Built for agent-to-agent calls. No subscriptions. No dashboards. Just a clean x402 micropayment (0.001 USDC on Base) and a signed JSON response you can pipe directly into your decision logic. All scoring methodology is open and auditable on GitHub. Zero data retention.
