preflight402

One free call before your agent pays. Probes the URL (no wallet, payment, or auth) and returns a trust-preview.v1 verdict: liveness and latency, TLS validity, the 402 payment handshake with protocol detection (x402 v1/v2, MPP-capable), detected networks/asset/price with a USD estimate, ERC-8004 identity binding with Sybil-filtered reputation for the payee (which can adjust the recommendation), and a proceed / caution / avoid recommendation with human-readable reasons. Paid-tier fields (uptime history, reseller analysis) are present but null on the free tier.
