Configuration

Variable	Required	Secret	Description
AGENT_PRIVATE_KEY	—	yes	Private key of your own EVM wallet holding USDC on Base, used to pay for paid tools. Optional: without it only the free catalog and sample tools return data. Use a dedicated low-balance wallet, never a main wallet. It is read locally to sign payments and is not sent anywhere.
MAX_USDC_PER_CALL	—	—	The most, in US dollars, the server will pay for a single call. A request priced above this is refused. Must be a positive number. The dearest call is $0.25.
BLOCKCHAINIQ_BASE_URL	—	—	Base URL of the API. Only change this to test against another deployment.
BLOCKCHAINIQ_NETWORK	—	—	The one network the wallet will pay on: base (Base mainnet) or base-sepolia (testnet, only for a test deployment). Payment requests on any other network are refused.
