Read a 402 challenge, authorize payment with your wallet, retry with PAYMENT-SIGNATURE. Never pay a receipt hash manually. Successful responses include PAYMENT-RESPONSE. Full upstream failure returns503 without settlement. Evidence includes exact-block contract code and token metadata, proxy slots, available security flags and market observations, and missing-source explanations. Evidence is not a guarantee of safety or an investment recommendation.
