Environment Variables

WALLET_PRIVATE_KEY(str)

Secret

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

SERVER_URL(str)

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

MAX_PAYMENT_USDC(str)

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.
