This one needs environment variables set before it will start: EVM_PRIVATE_KEY (0x… private key of a dedicated hot wallet holding USDC on Base mainnet; each tool call pays for itself. Omit to run in quote mode (tools return prices and payment requirements instead of data).), X402_MAX_PRICE (Maximum USD price per call; more expensive tools are refused before any payment. Default 0.50 (10x headroom — prices currently range $0.001-$0.05); lower it to cap spend harder.). The author declared them in the registry entry; get the values from the project itself.
