Parameters from the server's own tool schema.
This tool is directly involved in financial authorization decisions for paid tool calls, manages spend caps, processes USDC payments on Base/Solana, and produces spend ledger entries. Misuse could allow or deny financial transactions, manipulate payment guards, or bypass spend controls — making it a Financial category tool with critical severity due to its role as a payment authorization gatekeeper.

Evaluate the next x402 quote or paid-tool call against buyer-owned spend caps, route allowlists, payTo/network expectations, recent spend history, consecutive failures, and receipt evidence. Returns an allow/manual_review/deny decision, spend ledger entry, MCP and Flowise guard config, runtime snippet, and repeat-payment audit schema. This deterministic endpoint does not call an upstream model. Pay up to $0.012 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised. Exact fixed-price payment and Base upto token-metered payment are both accepted when clients support them; upto settlements use actual response usage, a 0.0001 minimum, and the selected tier price as the cap.
