This one needs environment variables set before it will start: AGENT_PRIVATE_KEY (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.). The author declared them in the registry entry; get the values from the project itself.
