Parameters from the server's own tool schema.
This tool commits financial obligations by processing x402 USDC payments on Base or Solana per request. It orchestrates payment receipts and financial transaction metadata for autonomous agents, making it Financial category. The blast radius is high because an AI agent could trigger repeated microtransactions autonomously without human oversight, accumulating costs through metered or fixed-price payment flows.
From the tool's definition 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
