Configuration

Variable	Required	Secret	Description
K_DATA_PRIVATE_KEY	yes	yes	Private key of a dedicated wallet holding USDC on Base. Each tool call spends from it. No ETH needed - x402 settles off-chain and the facilitator pays gas.
K_DATA_MAX_SPEND_USD	—	—	Hard cap on cumulative spend for the session. The server refuses any call that would exceed it.
K_DATA_BASE_URL	—	—	Point at a different K-Data deployment.
