GET /api/x402/b20-gate

live

🆕 The single call before trading a Base-native B20: seize (burnBlocked) + freeze (Policy Registry) + rebase + pause + uncapped-mint, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Pass wallet= to also check if YOUR address is already blocked on that token. The B20 tool to bind first.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
