Parameters from the server's own tool schema.
This tool is explicitly designed to execute financial payments — it generates and runs payment execution assets using USDC on Base or Solana networks, committing real financial transactions up to $4.90 per request. Even though it claims to never pay the target endpoint directly, it produces runnable payment execution code and handles x402 metered billing settlements.

Premium GPT-5.5 x402 buyer execution agent that turns a paid route, budget cap, runtime, payTo/network expectation, and receipt policy into runnable Node, Python, Bash, MCP, and Flowise payment execution assets. The service never asks for private keys and never pays the target endpoint. Pay up to $4.90 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised.
