Environment variables

• AGENT_PRIVATE_KEY secret Private key of your own EVM wallet holding USDC on Base, used to pay for paid tools. Optional: without it only the free catalog tool returns 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 default is $2.00, which covers every resource today (the dearest is $0.50) and the $2.00 Analyst pack.
• 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.
