Server instructions

x402 micropayments MCP (USDC on Base). Route by domain: x402.* buyer/seller HTTP 402, commerce.* quota/credits/Stripe, swarm.* composite research resale, pulse.base settlement timing, ops.metrics host health, city.* US open-data property compliance. Buyer path: x402.discover → x402.probe → x402.pay_and_fetch. City path: city.list → city.sample → city.check. Pro quota: commerce.pro_requirements → pay → commerce.activate_pro. Credits: commerce.credits_requirements → pay → commerce.purchase_credits. Public seller hosts have no spend key — probe tools still work; pay-and-fetch needs EVM_PRIVATE_KEY. Every tool response includes commerce meta.
