Environment variables

  • CORTEX402_WALLET_PRIVATE_KEY required secret Private key (hex, 0x-prefixed) for an EVM wallet on Base mainnet holding USDC. Used to sign EIP-3009 transferWithAuthorization for each call. Easiest funding: Coinbase Wallet → Buy → USDC on Base network → debit card (~$5 covers ~50 calls).
  • CORTEX402_BASE_URL Override the API base URL. Defaults to https://cortex402.vercel.app — only set this for staging or local development.
  • CORTEX402_MAX_PAYMENT_USDC Per-call payment ceiling in USDC. Defaults to 5.00 (covers sanctions $0.50, aviation $0.10, property $2.00 with headroom). Raise if calling other x402 endpoints through this server.
