Environment / auth

K_DATA_PRIVATE_KEY
required
secret
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.
