Generate a deterministic buyer integration package for an x402/MCP service
Generate a deterministic buyer integration package for an x402/MCP service: MCP remote server config, Claude Desktop-style config hints, curl discovery checks, x402 quote test commands, endpoint selection, spending caps, and verification checklist without calling an upstream model. GET variant for agents, crawlers, and wallets that prefer query parameters over a JSON body. Pay up to $0.006 per request with x402 USDC on Base.
