Is this x402 endpoint safe to pay? Vet an unknown seller BEFORE paying: pay/avoid verdict, 0-100 trust score, live 402 probe, scam flags (payTo hijack, bait-and-switch pricing, honeypot, wrong asset) and an on-chain check of the receiver on Base. Reads x402 v1 (body) AND v2 (PAYMENT-REQUIRED header) — body-only checkers call live v2 services dead. ?endpoint=url; omit for a trust-ranked catalog.
