Verify x402 endpoints before your agent spends. Three tools: verify (SPEND/CAUTION/INVESTIGATE/DO NOT SPEND backed by 50K+ services), passport (full trust identity), risk_check (deep assessment). No API keys, no signup.
Before an AI agent pays an x402 endpoint, checks whether it's safe to pay: liveness, scam/anomaly scan (payTo hijack, bait-and-switch, honeypot), and on-chain receiver verification. ~70% of x402 endpoints are dead or scams.
