$npx -y blockchainiq-x402-mcp@0.1.1 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 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.
