Server instructions

On-chain data tools for Base Mainnet. Each tool is priced per call in USDC via the x402 protocol. Free trial: the first call per IP every 24h is free on basic endpoints (<= $0.003); premium endpoints (e.g. token-due-diligence, base-market-snapshot) are always paid. Over MCP only the free-trial call is served; paid calls use the REST endpoints with an x402 client (PAYMENT-SIGNATURE header).
