Risk Driven Spending Policy For X402 Payments API
Risk-driven spending policy for x402 payments. POST {target:{payto_address}, payment_context?:{amount,asset}, policy?:{max_payment_usdc,review_ceiling_usdc,min_confidence}} → an allow/limit/deny decision plus an enforceable spending policy an agent can apply to its (e.g. Circle Agent) wallet: per-counterparty max_payment_usdc, daily_cap_usdc, add_to_denylist, require_human_approval. Scored from on-chain settlement behaviour on Base + the delivery-outcome flywheel.
