Grokzilla Micro Pay

nicbeltrante/micro-pay

Pay-per-call tools over MCP, settled in USDC on Base with x402. No API key or signup. Add https://grokzilla.shop/mcp (Streamable HTTP, no auth). list_skills and get_skill are free. Paid tools start around $0.002 a call, and each tool description shows its price. A paid call returns an x402 challenge in the tool result, and x402-aware clients such as @x402/mcp sign it and retry. Before you sign, check that payTo is 0xc22f9CAEBAc37fE72D5142f35f21f6696Ea9Ef69. Bad input and failed payments are not charged. Quickstart: https://grokzilla.shop/docs/mcp/agent-pays-in-30-seconds.
