Environment / auth

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