Api Endpoint

Agent Utility Suite

Preflight before paying any x402 endpoint: validates its 402 challenge (network, amount, asset, payTo, timeout, Bazaar declaration), prices it in USD, screens the payTo wallet (OFAC, wallet vs token contract) and shows real usage (Bazaar 30-day calls and unique payers). Budget check with max_price_usd. ok_to_pay / caution / do_not_pay. $0.003 USDC per call.
