  • WALLET_PRIVATE_KEY

    Funded Base wallet private key for x402 payment signing (optional; without it, paid tools return the 402 requirements).

    Format: string
    Optional
  • SERVER_URL

    true402 API base (default https://true402.dev/api). Must be https (or localhost) — the signer refuses to send a payment over cleartext.

    Format: string
    Optional
  • MAX_PAYMENT_USDC

    Client-side per-call spend ceiling in USDC (default 0.10). The signer refuses to auto-pay a 402 whose amount exceeds this — protects the wallet from a hostile endpoint.
