Buyer-owned x402 wallet signing safety pack for agents and wallets. Returns typed-data, calldata, chain, spender, allowance, receipt, and private-key boundary checks after payment. First-purchase activation is https://gpt55.558686.xyz/x402/wallet-signing-safety-pack.json and the dedicated buyer runtime is https://gpt55.558686.xyz/x402/wallet-signing-safety-pack-first-payment-client.mjs. The standard Payment-Required header now includes firstPaymentClient, paymentClientUrl, paymentActivationUrl, and sameRequestRetryRequired so header-only x402 clients can download the buyer-owned runtime, sign locally, and retry the same request with X-PAYMENT. Private keys are never sent to GPT55; use PAY_REAL_X402=1 EVM_PRIVATE_KEY=$EVM_PRIVATE_KEY in the downloaded client only from the buyer environment. Live quote is $0.018 exact x402 Base USDC.
