This one needs environment variables set before it will start: WALLET_PRIVATE_KEY (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.). The author declared them in the registry entry; get the values from the project itself.
